The private investment response to structural reforms in developing countries is of paramount importance, both for the future economic growth and the survival of the reforms themselves. By employing a sample of countries, recipients of World Bank Structural Adjustment Loans, the present paper...

The AEL (aid effectiveness literature) studies the macroeconomic effect of development aid using cross-country or panel data econo¬metrics. It contains about 100 papers of which 43 study whether development aid increases accumulation in the recipient country. Taking all 43 aid-accumulation...

The AEL consists of empirical macro studies of the effects of development aid. At the end of 2004 it had reached 97 studies of three families, which we have summarized in one study each using meta-analysis. Studies of the effect on investments show that they rise by 1/3 of the aid – the rest...

In this paper we investigate the effects of different fiscal policies on the firm choice to produce underground. We consider a tax evading firm operating simultaneously both in the regular and in the underground economy. We suggest that such a kind of firm, referred to as moonlighting firm, is...

Although much attention has been paid to the polarization of national labor markets, with employment and wage growth occurring in both low- and high- but not middle-skill occupations, there is little consistent evidence on cross-country differences in this process. I analyze job polarization in...

Do specialists exit the firm increasingly outsourcing its research and development (R&D) work? Although this question is critical in understanding how R&D outsourcing links to innovation performance, the answer is not yet clear. This paper proposes that the optimal level of firm’s internal...

This paper estimates a wage growth equation containing human capital variables known from the traditional Mincerian wage equation with year, worker and firm fixed effects included as well. The paper thus contributes further to the large empirical literature on unobserved heterogeneity following...

This paper estimates a Mincerian wage equation with worker, firm, and match specific fixed effects and thereby complements the growing empirical literature started by the seminal paper of Abowd, Kramarz and Margolis (1999). The analysis takes advantage of the extensive Danish IDA data, which...

Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model e show that the...

This paper analyses the implications of real wage rigidities in a stochastic two-country general equilibrium model. It is shown how real wage rigidities in one country affect welfare in both countries. Assuming that the choice of whether or not to adopt flexible wages is in the hands of labour...
