| Abstract: | This paper introduces a novel econometric framework for identifying and modeling bank business models (BBMs), which dynamically evolve in response to changing f inancial and economic conditions. Building on the stochastic frontier literature, we extend the traditional cost-efficiency models by decomposing inefficiency into persistent and transient components. We propose a Bayesian nonparametric approach that adapts to the data through an infinite mixture model with predictor-dependent clustering, enabling a flexible classification of banks into distinct business models. Our method, based on the Logit Stick-Breaking Process (LSBP), provides a data-driven way to capture the heterogeneity in bank strategies, allowing for dynamic transitions between business models over time. This model offers a significant advancement over existing parametric and kernel-based approaches by combining the scalability of nonparametric methods with efficient computational routines. We apply the model to a dataset of European banks and identify four distinct business model clusters, providing novel insights into the evolution of bank performance and efficiency. Our findings contribute to the growing literature on the identification and measurement of bank business models, offering valuable implications for policy and regulatory frameworks |

| Abstract: | Abstract We examine the relationship between remote work intensity and labor productivity using a survey of Finnish business leaders conducted in late 2024. The results show a positive but complex relationship between remote work and productivity, which is characterized by an inverted U-shape indicating that moderate levels of remote work are associated with the highest levels of productivity. Thus, a hybrid work model, combining on-site and remote work, is optimal for many companies. Management’s involvement in deciding the location of work and establishing clear remote work policies has an independent positive effect on productivity. The productivity effects of remote work are tied to companies’ and employees’ specific circumstances. Therefore, a company should not allow itself to fall into a random or accidental remote work situation. Instead, management and employees should continuously seek to optimize remote work arrangements for the long-term success of the company. At the very least, discussing the extent and ground rules of remote work should not be taboo. |

| Abstract: | We argue that capital misallocation arises endogenously due to incomplete consumption insurance. We model risk-averse entrepreneurs with heterogeneous productivity who face idiosyncratic output shocks and choose how much capital to rent before uncertainty unfolds. We show that incomplete markets operate as correlated distortions, leading to a reallocation of capital from more to less productive firms relative to the complete markets benchmark. Using Portuguese administrative data, we document that capital misallocation is greater in locations and industries with higher output shock volatility, consistent with our framework. Leveraging the structure of the model, we show that completing insurance markets increases aggregate productivity and income by 64% and 97%, respectively. |

| Abstract: | Health efficiency remains high before and after COVID-19. This could be attributed to devolved hospital management system which has brought public financial management services closer to the hospital and increased effectiveness in delivery of services. Similarly, there were also variations on health efficiency with some hospitals recording low and high efficiencies, which can also be attributed to hospital management. |
