Assessing the effect of educational programs on public schools’ performance

This paper provides evidence on the effectiveness in the implementation of an educational program which offered public schools in Catalonia (Spain) the opportunity to improve the quality of educational provision. We employ a difference-in-differences approach on rich balanced panel data of public schools. The results confirm that the program did effectively improve students’ achievement and reduce absenteeism, albeit not for all modules and school types or across all years. Our results highlight that it is important to condition the delivery of resources upon specific academic goals depending on the characteristics of the treated population. Additionally, program results suggest the need to enhance educational program design in order to get better evaluation feedback.

The volatility of world trade in the 21st century: Whose fault is it anyway?

This paper explores the drivers of the volatility of international trade. It decomposes trade growth into six components that have gained attention in the literature and studies their contribution to overall volatility. It yields three main findings. First, trade volatility in the 1990–2015 period is mostly explained by a common factor, changes in the gravity‐related characteristics of a country's trading partners and country‐specific factors. Product composition and the identity of trading partners appear to be less important in explaining volatility. Second, the pre‐2009 decline in volatility and the post‐2009 increase in volatility appear to be driven by different factors. The former is mostly explained by a decline in the variance of country‐specific factors; the latter appears to be driven by an increase in the volatility of common factors. Third, diversification is a likely force behind the steady decline in the volatility stemming from country‐specific factors, especially in developing countries.     

Does socially responsible mutual fund performance vary over the business cycle? New insights on the effect of idiosyncratic SR features

This study analyses the performance and market timing of US socially responsible (SR) mutual funds in relation to business cycle regime shifts and different grouping criteria: Ethical strategy focus, SR attributes scores and Morningstar category. Different methodologies are applied and results highlight the importance of considering specific benchmarks related to the investment style in evaluating the SR fund performance. Our results show that, in aggregate, the abnormal performance of SR funds is negative and significant in expansion periods, but no significant differences are found in recession periods. When specific benchmarks are considered, performance improves in recession periods, particularly for environmental funds, those with high SR attributes scores, and funds from the nine Morningstar style box categories. Market timing of SR funds takes positive values and is partially significant. Previous evidence of negative timing after a recent financial crisis vanishes when specific benchmarks are considered. For comparative purposes the performance of conventional US mutual funds is also analysed. There are no significant differences between the performance of SR and conventional mutual funds when a fair comparison is made within the same style categories. When all the SR funds are considered, they underperform conventional funds in expansion sub‐periods, but in recession sub‐periods they perform better, although the differences observed are not significant.     

Home Automation—A Fast - Expanding Market

In recent years, a host of companies have tried to bridge the technology gap between home automation systems. This collective effort has led to the development of technologies that have triggered the beginning of device interoperability. A seamless ecosystem is being created that aims to improve comfort for dwellers, improve efficiency of homes, and, as an additional result, will create a massive market for home automation devices. Our research revealed that the home automation market has been growing at an enormous pace and additional integration of technologies would continue to stimulate demand even more, further diminishing costs and thereby reducing the exclusivity of the market by bringing them to the masses. © 2016 Wiley Periodicals, Inc.     

An assessment of another decade of capital controls in Colombia: 1998–2008

We explore the effectiveness of capital controls in Colombia. We analyze the impact of administrative restrictions to capital flows on aggregate capital flows, the composition of capital flows, the real exchange rate, and economic activity using restricted versions of vector error correction models (VEC) that control for exogenous global financial conditions. The models are estimated using monthly data ranging from August of 1998 to May of 2008. In addition we estimate GARCH models to identify if capital controls have had relevant impacts on the volatility of the nominal exchange rate and of other relevant asset prices. These models are estimated using weekly data covering the same time period. Results suggest that the capital controls used since 1998 have been ineffective in reducing capital flows and the trend of the Colombian peso to appreciate. In addition there is no evidence suggesting a change in the composition of capital flows induced by capital controls. We find some evidence in favor of capital controls reducing nominal exchange rate volatility at high frequencies.     

Misallocation and productivity

A large portion of differences in output per capita across countries is explained by differences in total factor productivity (TFP). In this article, we summarize a recent literature — and the articles in this special issue on misallocation and productivity — that focus on the reallocation of factors across heterogeneous production units as an important source of measured TFP differences across countries.     

Foreign Banks and Credit Volatility: The Case of Latin American Countries

The number of foreign banks in Latin America increased substantially over the period 1995–2001, prompting a debate on the potential consequences for host countries. Discussions focused on efficiency, the impact on competition and product market diversification in the banking industry, and the quality of the regulatory environment, among other issues. Against this background, this paper uses ARCH techniques to test the impact of foreign banks on both the level and the volatility of real private bank credit in a panel of eight Latin American countries, using quarterly data over the period 1995–2001. The empirical findings show that, together with financial development, the presence of foreign banks has contributed to reducing real credit volatility, improving the buffer shock function of the banking sector.     

Beyond Altruism and Self-interest: The Growing Importance of External Factors in the Determination of Remittances Flowing to Latin America

Remittances have become an important and reliable source of funds for many developing countries, affecting the well-being of its population and the performance of their economies. However, challenging conditions in the economies were migrant workers reside has unveiled the increasing importance of external factors in determining their ability to send money back home. This study relies on migration patterns to create migration and distance-weighted measures of external condition, and uses the Arellano and Bond dynamic panel methodology to gauge the relevance of these external macroeconomic conditions during the 1995–2015 period for a set of 18 Latin American countries. The results indicate that external conditions, irrespective of the way in which they are measured, have a positive and statistically significant effect on the amount of remittances flowing into the region, and that such effect go beyond differences in levels, as relative differences prove to be important as well. While the results also show that remittances are inversely related to the income level of receiving countries and that these flows respond positively to better economic performance and higher interest rates in the receiving country, such altruistic and self-interest factors are less consistent than the one found for foreign economic activity.
