  1. By: Njindan Iyke, Bernard
    Abstract: In this paper, we examine the role of relative productivity growth in real misalignment of exchange rates in Latin American countries. Specifically, we verify the validity of the Penn Effect for selected countries in this region. Our sample consists of fifteen countries from the Latin American region for the period 1951 to 2010. We employ both short- and long-panel data techniques, which allow us to experiment with estimators suitable for short and long time dimensions of panel data. The Penn Effect is found to be supported for the entire sample, and for subsamples. Relative productivity growth is dominant in the real exchange rate movement during periods of mild or weak speculative attacks, as compared with periods of severe speculative attacks. To correct for real misalignment of currencies in Latin America under speculative attacks, relative productivity growth must be sizeable.

    Abstract: This paper investigates direct and spillover effects of a social information campaign aimed at encouraging residential water savings in Colombia. The campaign was organized as a randomized field experiment, consisting of monthly delivery of consumption reports, including normative messages, for one year. Results indicate that social information and appeals to normbased behavior reduce water use by up to 6.8% in households directly targeted by the campaign. In addition, we find evidence of spillover effects: households that were not targeted by the campaign reduced water use by 5.8% in the first six months following the intervention. Nevertheless, neither direct nor spillover effects can be attributed to social networks for any of our chosen proxies of social and geographic proximity.

  3. By: Lachaud, Michee Arnold (University of Connecticut); Bravo-Ureta, Boris E. (University of Connecticut); Ludena, Carlos E. (Inter-American Development Bank)
    Abstract: This study estimates Climate Adjusted Total Factor Productivity (CATFP) for agriculture in Latin America and Caribbean (LAC) countries, while also providing comparisons with several regions of the world. Climatic variability is introduced in Stochastic Production Frontier (SPF) models by including average annual maximum temperature, precipitation and its monthly intra-year standard deviations, and the number of rainy days. Climatic conditions have a negative impact on production becoming stronger at the end of the 2000s compared to earlier periods. An Error Correction Model is applied to investigate catch-up and convergence across LAC countries. Argentina defines the frontier in LAC and TFP convergence is found across all South American countries, Costa Rica, Mexico, Barbados and The Bahamas. Using IPCC 2014 scenarios, the study shows that climatic variability induces significant reductions in productivity (2.3% to 10.7%), over the 2013-2040 period.
