Gender differences in productivity rewards: the role of human capital

In this paper, we evaluate the gender wage gap component due to differences in characteristics’ rewards in Italy. The main focus is on the relationship between human capital characteristics and gender differences in rewards. We propose a methodology that combines the quantile regression analysis with non-parametric procedures for the estimation of the probability density functions of reward differentials in order to evaluate the evolution of the gap due to human capital characteristics. The analysis is carried out on Italian data taken from the latest available cross-section of the European Community Household Panel (2001). Our study suggests that education can be a good productivity signal and helps reduce the range of the gap; furthermore, highly educated women experience lesser gender-based pay differences as the length of the employment relationship increases.     

Gender differences in financial performance: new empirical evidence

This article provides new empirical evidence on gender differences in self-reported and observed financial performance. Using a quasi-experimental framework, comparing people who live in a matrilineal and a patrilineal environment in India, the results show that no significant gender differences in observed and self-reported performance exist among respondents who belong to the matrilineal culture. In contrast, women who live in a patrilineal environment self-report more often than men that they are not dealing well with economic and financial problems. However, no significant gender differences in observed financial performance are found.     

Economic freedom and social capital: pooled mean group evidence

This article uses annual US-state-level data from 1986 to 2004 and pooled-mean group estimation based on Pesaran et al. (1999) to examine whether economic freedom influences social capital. We find economic freedom has a negative effect on our social capital measure. This result is driven by the labour market component of freedom which is indicative of the relationship between labour market freedom and Olson-type group social capital.     

Reinterpreting social pacts: Theory and evidence

We investigate the empirical determinants of social pacts over the 1970–2004 period. We adopt a political economy approach, showing that governments are more likely to sign a pact when the cost of a conflict with trade unions is relatively larger. Such a cost depends on macroeconomic variables and on measures of social conflict and union strength. These findings are remarkably stable across sub-periods, in apparent contrast with previous contributions that emphasised differences between first- and second-generation pacts. Our interpretation is that pacts were different across periods because the policy issues changed, but the incentives to seek union consensus did not.     

A new approach to capital flows: Theory and evidence

This paper examines how an open economy determines its financial openness and deals with volatile capital flows when deciding to utilize them for output growth. We find that higher economic instability is an inevitable price paid for faster growth if a country permits wider openness without reversing its financial vulnerability. We prove that the country can leave its capital market wider open to achieve higher growth and lower instability if its financial system has been strengthened substantially. We show why some financially advanced countries request reluctant developing countries to liberalize their immature markets and how the conflict of interest between the two parties is formulated. The paper also presents a large sample of cross-country experiences with tradeoffs between growth and instability, with the observed evidence supporting our theoretical predictions.     

Investment in human capital and gender wage differences: evidence from the NLSY

This paper uses data from the National Longitudinal Survey of Youth (NLSY) to investigate gender differences in returns to various forms of human capital. Since the NLSY includes relatively detailed information regarding on- and off-the-job training, we place special emphasis on measuring gender differences in the incidence of and returns to formal post-school training. Also considered is the role of nonhuman capital factors such as industry and occupation in explaining the wage gap. It is found that about 60% of the gender wage gap in the sample is explained by mean differences in individual characteristics and market circumstances. This suggests a smaller role for discrimination in explaining the wage gap than previous research has found. The research indicates that training does not affect the gender wage gap. Also it is found that there is no statistically significant difference in the rate of return to other measures of human capital for women versus men. Our research suggests that the largest factors contributing to the wage gap are differences in the stocks of human capital for men and women, and differences in the distributions of men and women across industries and occupations.     

Family linkages,social interactions,and investment in human capital: A theoretical analysis

This paper introduces parent–child interactions into the Beckerian model of human capital. The acquisition of human capital, jointly determined by parental investment and child effort, is an equilibrium outcome of the intergenerational interactions, which is Pareto efficient within the family. We show that the equilibrium output of human capital is not affected by the parental authority over child behavior, but it is usually lower than the level that maximizes the instantaneous aggregate family welfare. In a family with more than one child, siblings not only compete for parental investments but also directly interact with each other in their effort choices. Exploring intragenerational connections and their interplay with intergenerational forces, we present a more complete theory of family linkages in human development and its implications for the rise and fall of families. Social interactions among children from different families induce intragenerational feedback effects that are further amplified by intrafamily interactions and accelerate regression toward the mean in the economic status of families.     

Productivity,capital intensity,and ISO 14001 adoption: Theory and evidence

The determinants of ISO 14001 adoption have been considered to fall into two categories: external pressure from environment‐oriented stakeholders or customers and internal need due to expected future benefits. In this study, we further elaborate the mechanism underlying firms’ adoption of the standard by investigating the inter‐relationship among firms’ productivity, capital intensity, and decision making regarding adoption. Applying a general equilibrium model, we show that under optimal conditions, highly productive firms can benefit more from adoption. Moreover, technological advancements potentially drive up firms’ capital intensity and this positively affects their incentive for adoption. The empirical practice using firm‐level data in Vietnam verifies our predictions with robustness. In addition, we find that the phenomenon outlined above becomes even more obvious in the manufacturing sectors.     

Corporate planning and capital investment

Based on interviews with corporate managers and reviews of corporate planning documents, corporate planning and implementation processes related to capital investment are examined in four large corporations. From the examination, models are developed and estimated on corporate plans and actual outcomes to explain corporate forecasts of capital investment, forecasts of changes in debt, and actual capital investment. The results of both the qualitative and quantitative data analyses are summarized and a new conceptual framework for the determinants of corporate capital investment is proposed.

本文针对现有的人力资本理论将人力资本投资形式局限于教育、培训、医疗、保健和迁移,而对其他投资形式关注不足的现实,认为适应于现代经济生活相关的思想观念、价值取向和道德规范,需要相关投入才会形成,这些投入也是人力资本投资不可或缺的形式,笔者将其概括为教化投资。经济转型过程凸显了教化投资的重要性。教化投资增强了人力资本的资源配置能力,在扩大个体人力资本存量的同时,还提升了社会经济价值,增加了社会资本。     

Government investment in natural capital

This paper presents a new approach to the measurement of natural capital. A distinguishing feature of this approach is the use of investment criteria that are consistent with the main features of physical capital, thus maintaining consistency in the measurement of different types of capital. This new approach was applied to the expenditures of the federal government in Canada as recorded in the Public Accounts for fiscal year 2004-05. My results indicate that, in 2004-05, total investment in natural capital by the federal government amounted to 2.6% of net budgetary expenditures. Spending on physical capital, the only component that is currently included as investment in the National Accounts, represented only 5% of total investment in natural capital.     

Gender differences in trust and reciprocity: evidence from a large-scale experiment with heterogeneous subjects

This article examines gender differences in an experimental trust game. Recent studies have shown that men trust more and that women are more reciprocal in laboratory experiments. Participants in these studies, however, are typically university students who may not be representative of the entire population. In this study, we use data from a large-scale experiment with heterogeneous subjects who are representative of the German population. We find that men exhibit not only more trusting behaviour, but also more reciprocating behaviour than women. Moreover, our results are indicative of age-dependent gender differences. For men, we find an inverse U-shaped relationship between age, on the one hand, and both trust and reciprocity, on the other; however, we do not find age effects for women.     

Repayment performance of joint-liability microcredits: Metropolitan evidence on social capital and group names

This study empirically tests the predictions of four primary theories applicable to joint-liability microcredit programs’ repayment performance using an administrative data in a metropolitan setting. We introduce a new variable, group names, as a proxy for social capital to capture cooperation, solidarity, and drive for success, which shows a significant positive impact of 9.9% on repayment performance. Precise calculations of residential distance between group members show a deterioration of repayment performance by 1.1% with a 15-min increase in minimum walking distance. The results also show that joint liability, sectoral diversification, type of sector that the borrowers facilitate, the ratio of new members in a group, characteristics of loan officers, loan amount, interest rate, income-loan amount coverage ratio, the existence of senior members, average education, and diversity in income streams significantly affect repayment performance.     

Human capital investment and debt constraints

When young individuals face binding debt constraints, their human capital investments will be insufficiently financed by private creditors. If generations overlap, then a well-designed fiscal policy may be able to improve human capital investments by replacing missing capital markets with an intergenerational transfer scheme. The optimal (balanced budget) fiscal policy in this context entails the joint provision of an education subsidy for the young and a pension program for the old, financed with a tax on those in their peak earning years. We demonstrate, however, that the desirability of such a cradle-to-grave policy depends crucially on the assumption of an exogenous debt constraint. If debt constraints arise endogenously for reasons of limited commitment, then the optimal (balanced budget) fiscal policy looks radically different. Furthermore, we find that cradle-to-grave type policy interventions may actually lead to lower levels of human capital investment as altered default incentives induce private creditors to contract the supply of student loans by an amount greater than the subsidy. In some cases, the constrained-optimal policy entails zero intervention. These results highlight the importance of taking seriously the reasons for why debt constraints exist.     

The nexus among foreign investment,domestic capital and economic growth: Empirical evidence from the MENA region

The objective of this paper is to estimate an econometric model for analyzing the interrelationship among foreign direct investment, domestic capital and economic growth in 13 MENA countries by using a ‘growth model’ framework and simultaneous-equation models estimated by the generalized method of moments (GMM) during the period 1990–2010. Our empirical results show that there is bi-directional causal relationship between foreign investment and economic growth, as well as domestic capital and economic growth, and there is uni-directional causal relationship from foreign direct investment to domestic capital for the region as a whole.     

Signaling in social network and social capital formation

This paper presents a model of social capital and social network formation. The key interaction within the model is that whom an individual chooses to become friends with affects the value (social capital) of the friendship. In the model, how a player searches for and then forms friendships reveals how willing she is to engage in cooperation with a potential friend. Individuals observe their local network structure (friends and cliques) and the actions of players within these. Willingness to cooperate is private information and is captured by the discount factor of an individual. Cooperative types have high discount factors and can signal their type by forming a clique through befriending a friend of a friend. Uncooperative types do not form these kinds of friendships because of the local observability of their actions to all members of a clique. Thus, when a player meets someone with whom she shares a friend, her belief that the individual has a high discount factor is greater than the population average. In this sense, people “trust” each other more when they share a friend in common. Finally, I relate the primitives of the model to characteristics of the implied social network by nesting the sequential equilibrium in an algorithm of network formation proposed by Jackson and Rogers (Am Econ Rev 97(3):890–915, 2007). The model highlights a trade-off between maximizing the total amount of social capital in a society and distributing it equitably across individuals.
