| Abstract: | This study aims to assess the implementation status of the 2018 RMG minimum wage provisions and propose a revised minimum wage for RMG workers in 2023, grounded in indicators outlined in the Bangladesh Labour Act (BLA). These indicators encompass various factors such as cost of living, production costs, productivity, product pricing, inflation, work nature, risk, business capacity, and socio-economic conditions at both local and national levels. Data was gathered through a primary survey conducted across 76 RMG enterprises and involving 228 RMG workers. Additionally, Key Informant Interviews (KIIs) and Focus Group Discussions (FGDs) were conducted. |

| Abstract: | Homestead, or tomorqa, farms play a key role in agriculture and food security in Uzbekistan. These small-scale farms are integral to the livelihoods of more than 5.5 million rural households, collectively utilizing over 500, 000 hectares of agricultural land, which accounts for nearly 15 percent of the country’s total arable agricultural land area.1 The significance of homestead farms is also underscored by their substantial contribution to the overall agricultural output of the country, producing the majority of horticulture and livestock products. In 2023, homestead farms produced approximately 62 percent of agricultural products, 37 percent of crop output, and an impressive 88 percent of livestock production. Recognizing their critical importance, the Uzbek government has positioned homestead farms at the heart of its poverty reduction strategy. This strategy includes the allocation of additional land to rural households, thereby expanding their capacity for agricultural production and improving the economic stability of rural communities. Furthermore, the government actively promotes the adoption of innovative agricultural technologies and practices by homestead farms. |

| Abstract: | The paper studies the effect of R&D investments by parent multinational corporations (MNC) and their affiliates on the decisions of those affiliates to purchase intermediate inputs across different locations. We first develop a theoretical model of R&D and sourcing decisions to provide potential mechanisms and to guide our empirical analysis. Our fixed-effects regression results imply that, first, higher affiliate R&D expenditures are associated with a higher share of the affiliate’s purchases from local firms. Second, higher R&D expenditures by affiliates in other countries (i.e., those under the same parent firm but located in a different foreign country) are associated with a higher share of affiliate purchases from those countries. Third, we find that the affiliate’s R&D expenditures are negatively correlated with the purchase share from the parent home country and from the parent firm. |

| Abstract: | Distributive concerns in transportation equity can be evaluated either in terms of inequality (e.g., how equal are distributions?) or sufficiency (e.g., how many and what kinds of people lack access to the transportation resources they need?). Sufficiency analyses offer more actionable insights that can be used to mitigate transportation disadvantage, but related analytical methods are not well developed. To advance this area of research and practice, this paper investigates three approaches to measuring sufficiency through the lens of public transport access to jobs: (i) Fraction of total regional destinations, (ii) Competitiveness with auto access, and (iii) population-weighted percentile measures. We use a class of decomposable Foster-Greer-Thorbecke poverty measures to understand the sensitivity of overall levels of disadvantage to the choice of disadvantage lines and other parameters, in the context of seven U.S. urban regions. We find that fractional and auto competitiveness measures produce similar results and are highly sensitive to the choice of disadvantage line, that population-weighted percentile measures may allow for better comparisons across demographic groups, and that by most reasonable definitions of transport poverty the vast majority of residents (80+%) in an area might be considered to be in transport disadvantage. |

| Abstract: | While interprofessional collaboration is essential to the quality of care, nurse managers tasked with promoting it are increasingly occupied by their role in managing resources, particularly human resources. Indeed, the context of absenteeism and shortage of paramedical professionals has worsened in recent years, leading nurse managers to dedicate the majority of their time to addressing the lack of paramedical staff by utilizing management tools. This research aims to understand whether support for interprofessional collaboration by nurse managers can be compatible with their role in workforce management. Through a case study conducted in a French university hospital, we demonstrate that managing the workforce by nurse managers entails making decisions that involve negotiated compromises with various stakeholders (doctors, paramedical staff, administrative staff, etc.): both workforce management and support for interprofessional collaboration are thus ensured by nurse managers through boundary work. We show that this boundary work operates at two levels (on the boundaries of other professional groups within the hospital on one hand, and on the professional boundaries of healthcare managers themselves on the other) and produces two effects. If the work aimed at blurring professional boundaries between the different hospital groups leads to strengthened collaboration in decision-making, the conservative or extensive boundary work conducted on the professional boundaries of paramedical managers allows them, conversely, to forgo the need to collaborate and to make decisions autonomously. It is the implementation of these decisions that then leads doctors, paramedical staff, and administrative staff to collaborate for their execution |
| Abstract: | Alors que la collaboration interprofessionnelle est indispensable à la qualité des soins, les cadres de santé qui sont chargés de la favoriser sont de plus en plus accaparés par leur rôle de gestion des ressources, en particulier humaines. En effet, le contexte d'absentéisme et de pénurie de professionnels paramédicaux s'est exacerbé dans les dernières années, ce qui conduit les cadres de santé à dédier la majorité de leur temps à faire face au manque de personnel paramédical en manipulant des outils de gestion. Cette recherche cherche à comprendre si le soutien à la collaboration interprofessionnelle par les cadres de santé peut être compatible avec leur rôle de gestion des effectifs. A l'aide d'une étude de cas menée dans un CHU français, nous montrons que la gestion des effectifs par les cadres de santé suppose de prendre des décisions qui constituent des compromis négociés auprès d'acteurs divers (médecins, paramédicaux, administratifs…) : la gestion des effectifs tout comme le soutien à la collaboration interprofessionnelles sont donc assurés par les cadres de santé au moyen d'un travail frontière. Nous montrons que celui-ci s'exerce à deux niveaux (sur les frontières des autres groupes professionnels de l'hôpital d'une part, et sur les frontières professionnelles des cadres de santé d'autre part) et qu'il produit deux effets. Si le travail visant à estomper les frontières professionnelles entre les différents groupes de l'hôpital conduit à renforcer la collaboration sur la prise de décision, le travail frontière conservateur ou extensif exercé sur les frontières professionnelles des cadres paramédicaux eux-mêmes leur permet au contraire de se passer du besoin de collaborer et de prendre des décisions de manière autonome. C'est l'application de ces décisions qui conduit ensuite les médecins, les paramédicaux et les administratifs à collaborer pour leur mise en oeuvre. |

| Abstract: | The fundamental principle of marginal pricing in electricity markets has been strongly challenged following the recent European energy crisis. One of the main criticisms is the inability of current markets to drive investments, as spot prices provide only short term information about supply, demand, and costs. This paper revisits the seminal work of Boiteux 1960 in the context of the recent energy crisis to discuss the fundamental assumption of adapted capacity, which underpins the equality between long term and short term marginal costs in the theory of marginal pricing. We argue that capacity is no longer adapted to current economic conditions in Europe. We then leverage techniques of mathematical programming to generalize the results of Boiteux 1960 and propose a market clearing mechanism that preserves the efficiency of current short term marginal pricing to induce optimal plants operations while also providing a long term investment signal when capacities are not necessarily adapted. Through an analysis of captured margins, our proposal, which differs only marginally from the current market clearing, identifies plants that should remain in the current mix and those that are no longer economical. We also discuss possible extensions of our proposal to accommodate capacity markets and price caps. Finally, we implement our models with the French power mix and demonstrate their advantages over the current market clearing mechanism using a realistic case study. |

| Abstract: | This paper calculates the exchange rate pass through (ERPT) with time constant and time varying coefficients for Colombia between 2006 and 2023. It then estimates the ERPT during four specific depreciation events during the period of analysis: the 2008 financial crisis, the 2014-2016 fall in international fuel prices, the COVID-19 pandemic and the post-COVID recovery. A Bayesian Vector Autoregressive model with exogenous variables (BVARX) model with time constant and time varying coefficients is used for the exercise. The results for time constant coefficients show that a 1 percentage point (p.p.) increase in the depreciation of the exchange rate leads to an increase in imported, producer and consumer inflation of 0.42 p.p., 0.15p.p., and 0.01 p.p. respectively in the first month of the shock. Time varying coefficient results suggest that the nature and the size of the shock result in a heterogeneous ERPT and monetary policy response. Moreover, higher ERPT in imported inflation and producer inflation does not seem translate into higher ERPT in consumer inflation. Further studies could look at: First, the nature of the ERPT on different types of inflation and why this is heterogeneous in a time varying analysis. Second, how the combined effect of different factors in the Colombian economy led to different monetary policy responses in each of the four episodes under analysis. |

| Abstract: | Many countries subsidize low-income employments or small jobs. These subsidies and their phasing out can generate labor market frictions and distort incentives. The German Minijob program subsidizes low-income jobs. It generates a 'Minijob trap' with substantial bunching along the earnings distribution. Since 2003, the newly introduced Midijob subsidy aims to reduce the Minijob-induced notch in the net earnings distribution. Midijobs reduce payroll taxes for employments above the Minijob earnings ceiling. We investigate whether introducing Midijobs reduced the Minijob trap. We apply a regression discontinuity design using administrative data and a difference-in-differences estimation using survey data. While in both cases our results show a small positive overall effect of Midijobs on transitions out of Minijobs, they are effective only for a narrow treatment group. |

| Abstract: | The current conflict between the Sudanese Armed Forces and the Rapid Support Forces in Sudan, which began in April 2023, has had a profound impact on the nation’s micro, small, and medium enterprises (MSME). Such enterprises are a vital part of the country’s economy and important to the food security of many Sudanese households. All MSMEs, including those in the agrifood sector, have faced severe disruptions due to the instability, rising inflation, and supply chain breakdowns brought on by the conflict. These challenges have destabilized MSMEs, affecting their financial viability, operations, and capacity to support local food security and provide employment. Agrifood MSMEs, in particular, serve as critical intermediaries between large firms and smallholders, supporting local economies and national food systems.2 The conflict has disrupted every aspect of agrifood value chains in Sudan, from input supplies and production to market accessibility. Agrifood entrepreneurs—especially women—have borne some of the heaviest impacts. Female entrepreneurs already face significant gender-based barriers in operating successful businesses, such as more limited access to finance, restrictive social norms, and mobility constraints. In this period of conflict, they now confront even greater challenges. |

| Abstract: | This paper is a comprehensive exploring of technology capability in 5G/6G TIS, explicitly focusing on the potential of remote surgery globally and in Germany. The paper's main contribution is its ability to anticipate new debates on the interplay between TIS and contexts, with particular emphasis on the national and international levels. Our findings, derived from a Bibliometrics study of industry-academic relationships, highlight crucial collaborations in Germany, positioning the country as a strategic actor in international TIS and, by extension, in applying 5G/6G technological systems to remote surgery due to its knowledge production capability. We propose policies that can stimulate interaction between smaller suppliers and larger companies, which can act as intermediaries and provide access to international markets. |

| Abstract: | This article probes the performance and mechanisms of the Maoist economy from 1950 to 1980, a period commonly regarded as a turning point that ushered in a new path for China's industrialisation and modernisation. Commonly, however, the welfare effect of this new path has been overlooked. The present research aims to fill this gap. Methodologically, this article re-conceptualises, re-examines, and re-assesses the Maoist economy with qualitative and quantitative evidence. This study applies a holistic two-pronged approach with (1) capital accumulation and re-investment, material production and consumption, and (2) mathematical conceptualisation and empirical modelling. The key findings suggest that the Maoist economy was a closed one with industrial dependence on agriculture in an urban-rural zero-sum game with inevitable constraints on workers' incentives for growth to continue. In the end of the Mao's era, agriculture declined, the size of industrial workforce stagnated, and the population was poor. This was not the end of the story, however. This failed industrial transition was itself highly influential as a subsequent point of reference used to justify the post-Mao reforms and opening up as a radical game changer that put China on a very different trajectory of growth and development. |

| Abstract: | Standard deficit accounting neglects the growth dividend: the amount by which annual GDP growth shrinks the debt-GDP ratio. America's growth dividend has more than doubled since the Great Recession because the debt ratio has more than doubled, leading to headline deficits that far exceed changes in the debt ratio. Each year's change in the debt ratio can be decomposed into three components: the primary deficit (non-interest spending minus tax revenue), interest payments, and the growth dividend. The sum of the latter two is excess interest: the impact of past debt on the debt ratio, roughly equal to last year's debt ratio times the excess interest rate (r-g)/(1+g) where r is the average nominal interest rate on federal debt and g is the nominal GDP growth rate. Excess interest remains slightly negative in CBO's baseline ten-year projection. Hence, current debt is sustainable in the CBO baseline despite high interest payments, and primary deficits entirely drive the unsustainable projected debt ratio path and provide a good guide for how the debt ratio is projected to change. However, America's higher debt ratio implies higher vulnerability to the risk that the excess interest rate turns persistently positive. |

| Abstract: | We address the liquidation problem arising from the credit risk management in decentralised finance (DeFi) by formulating it as an ergodic optimal control problem. In decentralised derivatives exchanges, liquidation is triggered whenever the parties fail to maintain sufficient collateral for their open positions. Consequently, effectively managing and liquidating disposal of positions accrued through liquidations is a critical concern for decentralised derivatives exchanges. By simplifying the model (linear temporary and permanent price impacts, simplified cash balance dynamics), we derive the closed-form solutions for the optimal liquidation strategies, which balance immediate executions with the temporary and permanent price impacts, and the optimal long-term average reward. Numerical simulations further highlight the effectiveness of the proposed optimal strategy and demonstrate that the simplified model closely approximates the original market environment. Finally, we provide the method for calibrating the parameters in the model from the available data. |

| Abstract: | The leather industry is an important contributor to Bangladesh’s export revenue. As such, this industry is vital in emerging as a promising sector, especially in export diversification and creating a more integrated industrial value chain. The industry benefits significantly from backward linkages in the value chain, consequently increasing its external competitiveness. In addition, there is substantial potential for producing higher value-added goods within the sector, which can be pivotal in attracting premium export prices. The leather industry provides Bangladesh with an optimistic avenue for greater participation within the global value chain (GVC), owing to its labour-intensive nature and horizontal linkages with the RMG industry (Razzaque, Uddin, & Rahman, 2018). |

| Abstract: | Purpose – The purpose of this paper is to critically examine the multinational oil companies’ (MOCs) corporate social responsibility (CSR) initiatives in Nigeria. Its special focus is to investigate the impact of the global memorandum of understanding (GMoU) on gender in the facets of palm oil value chain in the Niger Delta region of Nigeria. Design/methodology/approach – This paper adopts an explanatory research design using both descriptive and inferential statistics to answer the four research questions. We generated cross-sectional primary data from a sample of 1200 women selected from the nine states of Niger Delta region using multiple sampling techniques. Findings - Results from the estimation of a logit model and use of propensity score matching to determine the mean difference between variables in the treatment and control show that significant efforts have been made by the MOCs’ through their CSR in the areas that will help the women compete favourably in the oil palm value chain. Research limitations/implications – This study implies that MOCs’ CSR interventions that enhanced women acquisition of improved mechanised meals, accompanied by awareness creation and demonstration of value of improved processing technologies and practices to female processors will lift many women out of poverty in the Niger Delta. Social implications – This implies that fostering gender access to credit through GMoU interventions will improve extraction efficiency of female primary processors and enhance linkages between women producers/processors and large mills in palm oil value chain deliveries in the Niger Delta. Originality/value – This research contributes to gender debate in the agricultural value chain from a CSR perspective in developing countries and rationale for demand for social projects by host communities. It concludes that business has an obligation to help in solving problems of public concern. |

| Abstract: | Background: Population health across the UK has stagnated over the last 14 years, whilst health inequalities have widened. Much of this deterioration in health is driven by the wider determinants - the factors outside of health and care services that impact our health, such as our houses, our jobs, and our surroundings. Many of these factors are influenced or determined by local authorities. Accordingly, policymakers in local authorities should consider health in all their decisions; Health Impact Assessments (HIAs) can be used to do this. However, little is known about whether HIAs are widely used across local authorities for decisions made outside of town planning, or whether their use is beneficial; this study aims to investigate these questions. Methods: We designed and disseminated two surveys comprising both quantitative and qualitative questions for local authority officers working both within and outside of public health to gather experiences and opinions regarding HIA use in their organisations. Results: While HIAs are used across a number of local authorities for decisions made outside of town planning, their use is less widespread than for town planning decisions. Public health staff expressed good engagement with HIAs, and were largely positive regarding the ability of HIAs to improve population health and health inequalities, but expressed procedural issues with their use, such as difficulties completing HIAs and a lack of knowledge of where to seek help. Staff outside of public health were much less aware of HIAs generally, and none knew whether HIAs were used in their organisation, but many supported their implementation. Interpretation: Despite low sample sizes, these results suggest that uptake of HIAs within local authorities may be patchy, and highlights a potential disconnect between local authority officers working within and outside of public health as regards understanding and knowledge of HIAs; this may impact the effectiveness of more widespread use of these tools. These data highlight the need for targeted training and capacity-building initiatives within local authorities, alongside the importance of organisational and political support. By addressing these challenges, local authorities could foster a more collaborative, health-oriented culture, contributing to improved health outcomes and reduced health inequalities across communities. |

| Abstract: | This article presents a comprehensive methodology for processing financial datasets of Apple Inc., encompassing quarterly income and daily stock prices, spanning from March 31, 2009, to December 31, 2023. Leveraging 60 observations for quarterly income and 3774 observations for daily stock prices, sourced from Macrotrends and Yahoo Finance respectively, the study outlines five distinct datasets crafted through varied preprocessing techniques. Through detailed explanations of aggregation, interpolation (linear, polynomial, and cubic spline) and lagged variables methods, the study elucidates the steps taken to transform raw data into analytically rich datasets. Subsequently, the article delves into regression analysis, aiming to decipher which of the five data processing methods best suits capital market analysis, by employing both linear and polynomial regression models on each preprocessed dataset and evaluating their performance using a range of metrics, including cross-validation score, MSE, MAE, RMSE, R-squared, and Adjusted R-squared. The research findings reveal that linear interpolation with polynomial regression emerges as the top-performing method, boasting the lowest validation MSE and MAE values, alongside the highest R-squared and Adjusted R-squared values. |
