I am an assistant professor in the Economics Department at the University of Oslo. My research interests include topics in international trade, international finance, and migration.
Firms facing uncertain demand at the time of production expose their shareholders to volatile returns. Risk-averse investors trading multiple assets will favor stocks that tend to yield high returns in bad times, that is, when the marginal utility of consumption is high. In this paper, I develop a firm-level gravity model of trade with risk-averse investors to show that firms seeking to maximize their present value will take into account that shareholders discount expected profits depending on the correlation with their expected marginal utility of consumption. The model predicts that, ceteris paribus, firms sell more to markets where profits covary less with the income of their investors. This holds true even in the presence of complete and internationally integrated financial markets. To test the model's prediction, I use data on stock returns to estimate covariances between demand growth in export markets and expected marginal utility growth of investors in 21 countries. I then show that the covariance pattern is reflected in the pattern of these countries' exports across destination markets and time within narrowly defined product-level categories, as predicted by the model. I conclude that by maximizing shareholder value, exporters are actively engaged in global risk sharing. [PDF]
We develop a model that combines monopolistic competition on goods markets with skill-type heterogeneity on the labor market to analyze the effects of trade and migration on welfare and inequality. Skill-type heterogeneity and partial specificity to firms’ endogenously chosen skill requirements lead to endogenous worker-firm match quality, endogenous wage markups, and within-firm wage inequality. We identify novel effects of trade and migration. Trade enhances firms’ monopsony power on the labor market and worsens the average quality of worker-firm matches, but the gains from trade theorem survives. Integration of labor markets leads to twoway migration between symmetric countries. Migration enhances competitiveness on the labor market and tends to increase the average quality of worker-firm matches. Trade and migration are complements. Our model clearly advocates opening up labor markets simultaneously with trade liberalization. [CESifo Working Paper No. 7355, 2018] under review
