Foreign direct investment,economic freedom and economic growth: International evidence

In this paper, we investigate the systemic link between economic freedom, foreign direct investment (FDI) and economic growth in a panel of 85 countries. Our empirical results, based on the generalized method-of-moment system estimator, reveal that FDI by itself has no direct (positive) effect on output growth. Instead, the effect of FDI is contingent on the level of economic freedom in the host countries. This means the countries promote greater freedom of economic activities gain significantly from the presence of multinational corporations (MNCs).     

The theoretical and empirical evaluation of the third world brain drain to the United States: 1972-1987

"This paper is divided into four sections. Section I deals with theoretical issues behind labor migration in general with emphasis on 'brain drain'. Section II is concerned with an empirical analysis of third world professional immigration into the U.S. for the time period 1972-1987. Section III discusses policy implications to deal with [the] 'brain drain' problem."     

Temperature,rainfall and economic growth in Africa

Following a recent line of research, this paper investigates the aggregated effects of temperature and rainfall on economic growth in Africa. Our econometric approach is based on a reduced-form model and takes account explicitly of parameter heterogeneity and cross section dependence, relying on ARDL modelling and panel estimators with multifactor structures. We find clear supportive evidence of short- and long-run relations between temperature and per-capita GDP growth, while the role played by rainfall appears to be less important and the evidence on its statistical significance is less clear-cut. Very similar results are reported when the analysis is carried out by focusing solely on Sub-Saharan African countries or considering GDP growth per worker. This evidence is in sharp contrast to the results obtained via standard MG estimation and this confirms that, by not controlling for cross section dependence, traditional panel estimators are likely to provide misleading inference. The empirical results suggest that, far from adapting quickly to weather shocks, African economies appear to be significantly damaged by them. In the absence of corrective measures, the current trends in climate change may impose a progressively heavier burden on African countries.     

The response to incentives and contractual efficiency: Evidence from a field experiment

We use data from a field experiment to estimate worker reaction to incentives and the optimality of piece-rate contracts. Our estimate of the elasticity of output with respect to piece rates is 0.39. Regression methods cannot predict performance under hypothetical contracts. Therefore, we apply structural econometric methods (without imposing profit maximization) to evaluate observed-contract optimality. Using profit as a metric, we estimate the distance between observed and profit-maximizing contracts to be negligible. This suggests that observed contracts closely approximate optimal contracts under asymmetric information about worker ability. Under complete information, the firm could increase expected profits by 14 percent keeping workers indifferent to the observed piece-rate contract. Profits could increase between 44 and 49 percent if the firm exploited information about ability to reduce worker utility to the outside alternative.     

International migration,non-traded goods and economic welfare in the source country

"This paper examines the economic effects of emigration in a source country producing both traded and non-traded commodities. It is shown that, even if the economy faces fixed terms of trade, emigration can still affect the welfare of the non-migrants, and the direction of the effect in this context will always be negative." The focus is on migration from developing countries.     

Contests to become CEO: incentives, selection and handicaps

Should a firm favor insiders (handicap outsiders) when selecting a CEO? One reason to do so is to take advantage of the contest to become CEO as a device for providing current incentives to employees. An important reason not to do so is that this can reduce the ability of future CEOs and, hence, future profits. The trade-off between providing current incentives and selecting the most able individual to become CEO is the focus of this paper. If insiders are good enough (better or nearly as good as outsiders), incentive provision to insiders typically dominates and it is optimal to handicap outsiders, sometimes so severely that they have no chance to win the contest. However, if outsiders are sufficiently better than insiders, selection dominates and it is the insiders who are severely handicapped. This finding is in sharp contrast to the existing literature which has so far ignored this trade-off. In all, our model provides useful insight into contests to become CEO and rationalizes empirical regularities in the source of CEOs chosen by firms. In particular, our analysis helps to explain the lower tendency of firms in more heterogeneous industries and firms with a product or line of business organizational structure to select an outsider as CEO.     

Child fostering in Africa: When labor and schooling motives may coexist

The paper proposes a theoretical framework for understanding purposive child fostering in Africa, whereby a non-orphaned child is sent to live temporarily with relatives. In the model, adults decide whether to foster in or out a child in conjunction with other household choices, e.g. own time allocation between market and non-market activities, children's amount of work, and schooling. By allowing for positive externalities from fostering, and thus asymmetric motives for fostering in (labor) and out (human capital), the proposed framework predicts that school-age children are sent to better-off households and that some families may foster in and out simultaneously. The model identifies the conditions under which all actors involved, children included, may benefit from fostering arrangements, but also points to situations where fostering may become an opportunity to marginalize a subset of children. The paper aims to provide a sound theoretical foundation that sheds light on why there exists mixed empirical evidence on the effects of fostering on children's well being, and cautions against demonizing non-parent residence as unequivocally detrimental to children.     

International migration,economic policy and human capital accumulation: a simulation study

"This paper examines the economic policy implications of international migration and human capital accumulation within a dynamic general equilibrium model. Each country produces by means of physical and human capital of two types (skilled and unskilled labour). Along optimal growth paths in a world of diverging population growth rates immigration can only be beneficial when the free rider effect (i.e., not paying for training costs) exceeds the capital dilution effect of an increase in population growth. Under quite general conditions the optimal immigration rate is zero."     

International migration,non-traded goods and economic welfare in a two-class economy: A reply

This paper sketches a formal model of an economy producing traded and non-traded goods in which two classes of individuals are differentiated, each owning different endowments of capital and labor and allocating different proportions of their income to the consumption of each commudity. The effects of emigration on prices, income distribution and the real income of each class is then examined.     

Employment shifts, economic reform and the changes in public/private sector wages in Mexico: 1987–1997

Over the last decade, the public sector in Mexico experienced substantial fiscal reform, divestiture of public enterprises, and the elimination of many regulations affecting pay and employment. This study analyzes the changes in the public/private sector differences in wages during the 1987–1997 period. The results from analyzing microdata from the Encuesta Nacional de Empleo Urbano show that relative public sector wages increased from 1987 to 1997. Most of the relative wage increase in the public sector can be explained by increases in the price of skills and by changes in sorting across sectors. The results have important public policy implications since they suggest that public sector workers earn more and their wages have grown faster than those of their private sector counterparts. As such, policies contemplating public sector reform should take into account the effect of these measures on the inter-sectoral income distribution and the overall economic growth.

Political instability: Effects on financial development, roots in the severity of economic inequality

We here bring forward strong evidence that political instability impedes financial development, with its variation a primary determinant of differences in financial development around the world. As such, it needs to be added to the short list of major determinants of financial development. First, structural conditions first postulated by Engerman and Sokoloff (2002) as generating long-term inequality are shown here to have strong empirical support as exogenous determinants of political instability. Second, that exogenously-determined political instability in turn holds back financial development, even when we control for factors prominent in the last decade’s cross-country studies of financial development. The findings indicate that inequality-perpetuating conditions that result in political instability and weak democracy are fundamental roadblocks for international organizations like the World Bank that seek to promote financial development. The evidence here includes country fixed effect regressions and an instrumental model inspired by Engerman and Sokoloff’s (2002) work, which to our knowledge has not yet been used in finance and which is consistent with current tests as valid instruments. Four conventional measures of national political instability – Alesina and Perotti’s (1996) well-known index of instability, a subsequent index derived from Banks’ (2005) work, and two indices of managerial perceptions of nation-by-nation political instability – persistently predict a wide range of national financial development outcomes. Political instability’s significance is time consistent in cross-sectional regressions back to the 1960s, the period when the key data becomes available, robust in both country fixed effects and instrumental variable regressions, and consistent across multiple measures of instability and of financial development. Overall, the results indicate the existence of an important channel running from structural inequality to political instability, principally in nondemocratic settings, and then to financial backwardness. The robust significance of that channel extends existing work demonstrating the importance of political economy explanations for financial development and financial backwardness. It should help to better understand which policies will work for financial development, because political instability has causes, cures, and effects quite distinct from those of many of the key institutions most studied in the past decade as explaining financial backwardness.     

Intra-household labor supply,migration, and subsistence constraints in a risky environment: Evidence from rural El salvador

We investigate the use of intra-household labor allocation as a means of risk coping when subsistence constraints matter in rural El Salvador. We show that households increase the labor supply of its male members to the family farm and abroad in the US after being subjected to adverse agricultural productivity shocks. The latter is the result of a standard substitution effect, whereas the former is the result of subsistence concerns. Theoretically, these results are not at odds with each other if these events differentially impacted rich and poor households. We also show that the earthquakes of 2001 resulted in large reductions in the number of female members who were sent abroad and large increases in hours of domestic labor supplied by female members. We argue that this result is a consequence of subsistence motives because female labor supply at home increased despite lower remuneration.     

Labour migration in the enlarged EU: a new economic geography approach

This paper studies the impact of migration policy liberalisation on international labour migration in the enlarged European Union (EU) in a structural economic geography approach. The liberalisation of migration policy would induce an additional 1.80–2.98% of the total EU workforce to change their country of location, with most of migrant workers relocating from the East to the West. The average net migration rate is decreasing in the level of integration, suggesting that from an economic point of view no regulatory policy responses are necessary to labour migration in the enlarged EU.     

Abatement of agricultural pollution and economic incentives: The case of intensive livestock farming in France

Amongst possible economic incentives to encourage reduced nitrate contamination of water, this paper emphasizes a nitrogen tax as a possible solution. This finding is based on models estimated from panel data for 100 intensive livestock farms. For each farm a threshold is established (nitrogen units which can be spread per hectare without damage) above which there is an excess of nitrogen. The 100 farms can consequently be classified into two subsamples. The demand for nitrogen is derived for each sub-sample using the dual approach. Both categories are pooled together and a tobit model is estimated. This is used to derive total nitogen demand if all farms were under the threshold. A mineral nitrogen tax would lead to a reduced nitrate concentration in water supplies, because of a more efficient use of organic nitrogen together with a reduction in the use of mineral nitrogen in crop production.     

Eisenhower's economic strategy: Promoting growth and personal freedom by creating conditions favorable to the operation of a market-based economy

Here is considered the substance and goals of President Dwight D. Eisenhower's economic initiatives. The intention of these initiatives was to shift the relationship between public and private efforts in a way that would strengthen the underpinnings of the market-based and market-directed entrepreneurial economy, as well as enhance personal freedom. Also considered are the success of the initiatives, how the economy fared under the initiatives, and how the prospect for growth and improvement in the economy has been borne out since Eisenhower's administration.

Democracy and economic growth in Sub-Saharan Africa: a panel data approach

This paper studies the link between democracy and economic development for 28 countries of Sub-Saharan Africa for the period 1980–2005 in a panel data framework. A democracy index constructed from the Freedom House indices. A variety of panel data unit root and cointegration tests are applied. The variables are found to be integrated of order one and cointegrated. The Blundell–Bond system generalized methods-of-moments is employed to conduct a panel error-correction mechanism based causality test within a vector autoregressive structure. Economic growth is found to cause democracy in the short-run, while bidirectionality is uncovered in the long-run. In addition, the long-run coefficients are estimated through the panel fully modified ordinary least squares and dynamic ordinary least squares methods. Democracy has a positive impact on GDP and vice versa. These results lend support to the virtuous cycle hypothesis.     

AIDS mortality and its effect on the labor market: Evidence from South Africa

This paper investigates how HIV/AIDS has impacted the labor market in South Africa, focusing on its effect on wages and employment. This is done by matching individual level data with group specific cumulative AIDS mortality rates. Exploiting the panel nature of the data, I remove individuals whose productivity is most likely impacted by HIV/AIDS, and find evidence that cumulative AIDS mortality has led to reductions in wages of between 3 and 6% for the African population group (Black South Africans). Furthermore, I also find evidence that the epidemic has lowered employment in South Africa. This result is concentrated among those with the lowest levels of education and employment. Although not large in magnitude, these effects are widespread across a significant portion of the population, contributing to a substantial loss of income throughout the South African economy.
