The Baby Boom, Baby Busts, and Grandmothers

Studies in family economics and anthropology suggest that grandmothers are a highly valuable source of childcare assistance. As such, availability of grandmothers affects the cost of having children, and hence fertility decisions of young parents. In this paper, we develop a simple model to assess the fertility implications of the fluctuations in both output (as argued by demographers) and grandmother-availability induced child-care costs over the period 1920-1970. Model does a good job of mimicking the bust-boom-bust pattern during this period. When the child-care cost channel is shut down, the model’s performance weakens significantly; in particular, it fails to capture the bust in the 1960’s altogether.fertility, baby boom, baby bust, female labor-force participation, grandmother availability

Organization of innovation and capital markets

This paper develops a theory of the firm scope where not only research but also ordinary production employees can generate inventions. Separating research from production (“specialization”) solves the two-tier agency problem of inducing simultaneously research effort and managerial truthful-reporting but is costly when capital markets are imperfect. Improvements in capital markets, therefore, promote specialization, allowing a greater number of specialized firms to be established and also enabling them to undertake innovative projects with larger potential outcomes. Moreover, this capital market improvement effect is stronger for innovative activities that are less capital-intensive and that have weaker synergies with existing production activities. The model can help us understand the explosion of small company innovation in the U.S. since late 1970s and the contribution of venture capital to this change

Organization of Innovation and Capital Markets

There has been an explosion of innovation backed by venture capital since late 1970’s. Nonetheless, a great deal of innovation still occurs within large companies. In this paper, I investigate the factors that determine when innovation is performed by venture-backed firms and when by large companies. To this end, I develop a theoretical model in which development of new technologies and products requires the collaboration of researchers, executives, and suppliers of capital. I focus on the two-tier agency problem designed to provide simultaneously the right kinds of incentives for researchers and executives. I find that if capital markets function perfectly, it is optimal for innovation to be conducted by venture-backed firms: Specialization implicit in venture form of organization mitigates two-tier agency problems. If capital markets are sufficiently imperfect, however, it is optimal for innovation to be performed by large companies: they can use cheaper internal funds to finance innovation. I finally point to the role of policy in improving capital markets and hence innovation performance

Religion, Income Inequality, and the Size of the Government

Recent empirical research has demonstrated that countries with higher levels of religiosity are characterized by greater income inequality. We argue that this is due to the lower level of government services demanded in more religious countries. Religion requires that individuals make financial sacrifices and this leads the religious to prefer making their contributions voluntarily rather than through mandatory means. To the extent that citizen preferences are reflected in policy outcomes, religiosity results in lower taxes, which in turn implies lower levels of spending on both public goods and redistribution. Since measures of income typically do not fully take into account the part of income coming from donations received, this increases measured income inequality. We formalize these ideas in a general equilibrium political economy model and also show that the implications of our model are supported by cross-country data.religion, voluntary donations, taxation, redistribution, income inequality

Southeastern Europe: post-crisis prospects and risks

The Southeast European (SEE) countries have strong roots in social and historical terms. Their experience of the last couple of decades indicates, however, that SEE is in continual change and transformation: They want to attain more open societies, functioning markets and well-knit international affairs. This paper examines the economic prospects of the SEE countries from the eye of outsiders. Specifically, we investigate the strength of intra-SEE economic ties, stability at the nexus of financial and real sectors, propagation of shocks from the major economies of Europe to the SEE, and uncertainties surrounding the SEE countries. Along each of these dimensions, we maintain a comparative perspective, spatially relative to continental Europe and Turkey and temporally relative to the pre-crisis period
