Liquidity Constraints and Investment in Transition Economies

We use Bulgarian firm-level data to investigate the impact of liquidity constraints on investment performance. Internal funds are an important determinant of investment in most industrialized countries. We test whether internal funds are important for firm investment during the current transition process in Bulgaria. We use a simple accelerator model of investment to test whether liquidity constraints are relevant in the case of Bulgaria. Our estimations are based on data for the period 1993–95, prior to the Bulgarian financial crisis in 1996–97. It turns out that Bulgarian firms are liquidity constrained, and that firms' size and financial structure help to distinguish between firms that are more and less liquidity constrained. In our view, liquidity constraints can be given a different interpretation in the case of transition economies as compared to Western economies. A more in depth analysis of the data reveals that liquidity constraints, and consequently the access to external funds for Bulgarian firm investment, are to be seen against the background of soft-budget constraints and the failure of the financial system to enforce an efficient allocation of funds. In our view, the lack of liquidity constraints may actually be seen as a sign of financial weakness in the case of Bulgaria.     

The Effect of Marriage on Education of Immigrants: Evidence from a Policy Reform Restricting Marriage Migration*

We investigate the effect of immigrants’ marriage behavior on dropout from education. To identify the causal effect, we exploit a recent Danish policy reform that generated exogenous variation in marriage behavior by a complete abolishment of marriage migration for immigrants below 24 years. The reform influenced immigrants from countries with a high historical rate of marriage migration more than immigrants from country groups with a low rate. We find that the dropout rate for males increases by 25 percentage points as a consequence of marriage to a marriage migrant, whereas the effect for females is small and mostly insignificant.     

The structure and management of government research institutes: some problems and suggestions1

The open system model is applied to examine government industrial research institutes. Their observed ineffectiveness is in part accounted for by a growing discrepancy between organizational structure and activities and rapidly changing task environments. A number of suggestions for reorganizing the research institutes are offered. It is, however, indicated that in a change program aimed at promoting organizational effectiveness: (a) the focal organization's management could assume a more active role; (b) relevant parts of the environment should also be considered as targets of change.

Let the evidence speak again! Financial incentives are more effective than we thought

In this essay, the authors rejoin the debate about financial incentive effectiveness. They (a) briefly review the state of the literature in 1998, (b) highlight new meta‐analytic findings and update conclusions regarding the financial incentives–performance relationship, (c) address the myth that financial incentives erode intrinsic motivation, (d) provide explanations for the presumed failure of financial incentives and (e) offer some concluding thoughts and suggestions for future research.

International trade and child labor: Cross-country evidence

We explore the relationship between exposure to trade (as measured by openness) and child labor in a cross-country setting. Our methodology accounts for the fact that trade flows are endogenous to child labor (and labor standards more generally) by examining the relationship between child labor and variation in trade based on geography. We find that countries that trade more have less child labor. At the cross-country means, the data suggest an openness elasticity of child labor of − 0.7. For low-income countries, the elasticity of child labor with respect to trade with high-income countries is − 0.9. However, these relationships appear to be largely attributable to the positive association between trade and income. We consistently find a small and statistically insignificant association between openness and child labor when we control for cross-country income differences in the full sample, when we split the sample into different country groups, consider only trade between high- and low-income countries, or focus on exports of unskilled-labor intensive products from low-income countries. Thus, the cross-country data do not substantiate assertions that trade per se plays a significant role in perpetuating the high levels of child labor that pervade low-income countries.
