Stopping the exodus of women in science

A new study reveals that U.S. companies face a troubling brain drain: Fifty-two percent of female scientists, engineers, and technologists abandon their chosen professions. If companies understand why women drop out, however, they can create targeted interventions and head off a talent shortage.     

Civil Liberties, Democracy, and the Performance of Government Projects

This article uses a cross-national data set on the performanceof government investment projects financed by the World Bankto examine the link between government efficacy and governance.It demonstrates a strong empirical link between civil libertiesand the performance of government of projects. Even after controllingfor other determinants of performance, countries with the strongestcivil liberties have projects with an economic rate of return8–22 percentage points higher than countries with theweakest civil liberties. The strong effect of civil libertiesholds true even when controlling for the level of democracy. The interrelationship among civil liberties, civil strife, andproject performance suggests that the possible mechanism ofcausation is from more civil liberties to increased citizenvoice to better projects. This result adds to the evidence forthe view that increasing citizen voice and public accountability—throughboth participation and better governance—can lead to greaterefficacy in government action.

Land Invasions,Insecure Property Rights and Production Decisions

This paper investigates empirically the effect of land invasions on farm production decisions. The main hypothesis is that more invasions in a region are associated with lower investment, and in particular a bias towards annual crops as opposed to long‐term crops. We use a county‐level dataset for the state of Paraná, Brazil, from 2003 to 2007, with 1,995 observations. The panel data structure allows us to control for fixed effects, such as the formalisation of land titles and land concentration, which might be correlated with the intensity of invasions. An instrumental variable fixed effects model was estimated to avoid other sources of bias. Our main finding is that land invasions are associated with lower long‐term crop production and a higher percentage of annual crops, which could accelerate land degradation, and undermine environmental sustainability.     

SURVEYING THE ECONOMICS OF PLURAL MODES OF ORGANIZATION

Why do firms concomitantly rely on more than one organizational arrangement to procure/distribute a given input/product? In this paper, we systematically review and discuss the extensive path undergone by the literature exploring this issue: the so‐called plural forms. We address two main questions: how to explain the coexistence (and often the prevalence) of plural forms in many types of businesses? Are plural forms stable or a transitory phenomenon? We describe the most prominent motivations identified in the economics and management literature that drive firms to adopt plural forms and show that their vast majority are related to the mitigation of various types of agency/transaction costs. We also demonstrate that most of the available pieces of empirical evidence suggest the stability of plural forms over time. We conclude by demonstrating the path that has been trailed by the most recent developments.     

An Examination of Component Returns and Volatility for Country-Specific Equity Funds in Emerging Markets＇ Evidence From Asian Financial Crisis

This research aims to examine the daily return generating processes for country-specific funds in five east-Asian countries for the period 1995-2000. The effects of component returns and their volatility on the dollar denominated returns and volatility of U.S., international investors and the effects of exchange rate regimes on risk and return are also evaluated. The GARCH-M model is adopted, without the restrictive assumptions of linearity, independence, and constant conditional variance. The time frame, 1995-2000 captures a 30 months period prior to these East Asian countries aborting exchange rate stabilization/intermediate exchange rate regimes in response to the currency crisis. The decomposition of returns to holders of country-specific equity funds into the component returns due to changes in the exchange rate and the returns valued in the fund＇s foreign currency during a period of crisis provides additional information. This research provides evidence of the importance of examining component returns. With regards to the effects on volatility, both the conditional variances associated with the exchange rate returns and the returns denominated in the foreign currencies show some importance, especially the conditional variances associated with the returns denominated in the foreign currencies. With regards to the effects of return component, the exchange rate returns have a greater effect on the fund returns than foreign currency dominated returns.     

Trade Liberalization,Nature of Mergers and Employment

This paper investigates the roles of comparative advantage and market size in the international location of manufacturing production. Building on the conventional Helpman and Krugman (1985) general equilibrium framework, our analysis extends the present literature by incorporating both effects in the same model, while allowing trade costs to vary almost continuously from autarky to free trade. The main result of our exercise is that market size effects offset comparative advantage if countries have similar factor proportions. A large country with a slight comparative disadvantage in manufacturing production may thus be a net exporter of manufactures. A small country with the same comparative disadvantage would be a net importer of manufactures. When countries are very dissimilar in their relative factor endowments, land-abundant countries specialize in the production of food, irrespective of market size, if manufactures are a labour-intensive sector. Labour-rich countries of any size are manufacture cores. However, land-abundant countries with large markets can sustain a domestic manufacturing industry until trade costs are very low, and in some cases only specialize in agriculture at free trade.     

Fish Consumers: Environmental Attitudes and Purchasing Behavior

The objective of this study was to expand on the limited awareness of the U.S. fish consumer. Measures were tested through a Web-based national survey. The final survey consisted of 40 questions, including environmental awareness, food neophobia, fish consumption, reasons for consuming fish, and demographic variables. Correlations and t tests were used to analyze relationships between eating fish in restaurants and other variables. Hierarchical cluster analysis was used to segment respondents into two groups based on their environmental awareness and neophylic/neophobic attitudes. EcoFish consumers were more likely to be male, eat fish for health and the environment, and eat fish at restaurants significantly more than the Indifferent Fish consumers. Restaurants can use these results to market to eco-friendly, health-conscious fish consumers.
