Early Life Adversity and Children’s Competence Development: Evidence from the Mannheim Study of Children at Risk This paper investigates the role of early life adversity and home resources in terms of competence formation and school achievement based on data from an epidemiological cohort study following 364 children from birth to adolescence. Results indicate that organic and psychosocial risk...

This paper documents and analyses the volatility of economic growth in rich and poor countries. It concludes that whereas volatility has declined almost universally in advanced countries, the picture is more mixed for developing countries. The paper then concentrates on the case of India, where GDP volatility has declined over the past two decades. The evidence shows that the move away from agr...

Hidden Insurance in a Moral Hazard Economy We consider an economy where individuals privately choose effort and trade competitively priced securities that pay off with effort-determined probability. We show that if insurance against a negative shock is sufficiently incomplete, then standard functional form restrictions ensure that individual objective functions are optimized by an effort and in...

This study analyzes the market quality differences, in terms of liquidity and volatility, between Real Estate Investment Trusts (REITs) and non-REIT common stocks. The 2008 financial crisis has significantly influenced the market quality for REITs. Our findings reveal intraday patterns indicating a lower liquidity, higher volatility, and greater price impact for REITs than nonREITs for pre-cris...

A general equilibrium model of a small open economy is developed to analyze the optimal rate of inflation under discretion. Once agents’ welfare is the sole policy objective it is possible to show that openness and inflation no longer have a simple inverse relationship. A greater degree of openness may lead the policy maker to want to exploit the short-run Phillips curve more aggressively, even...

This short paper explores the complementarity between foreign aid and foreign direct investment (FDI). Recent studies on aid concluded that aid should come to an end or be reduced with a radical modification of the terms and conditions and FDI and trade should replace aid as the engine of development. In this paper, we argue that aid complements FDI and advances the efficacy of FDI in promoting...

We study pure exchange economies with symmetries on preferences up to taste intensity transformations. In a 2-person, 2-good endowment economy, we show that bilateral symmetry on each utility functional precludes a rectangle in the Edgeworth box as the location of Pareto optimal allocations. Under strictly quasi-concave preferences, a larger set can be ruled out. The inadmissible region is stil...

The opening of new markets or trade routes has resulted in the deliberate or accidental introduction of new species, while the growth in the volume of trade has increased the frequency of species introductions. We model the connection between landscape heterogeneity, resource extraction, the level of biodiversity, and the level of trade. We show that the invasion risks of trade reduce the socia...

I investigate the long-run implications of trade and technology diffusion through trade, when firms are heterogeneous and trade is costly. The paper integrates firm heterogeneity and trade into product innovation growth models from endogenous growth theory. Two specifications of the R&D process are considered. In the first, R&D uses labor and intermediate goods; in the second, it uses labor and...

Informal discussions on international trade attribute much importance to organizational differences. Nevertheless, economic theories of international trade have not been extended to incorporate this important element. This paper integrates theories of internal organization with a model of international trade by adding another dimension — how decisions regarding which ideas or projects to accept...
