This study analyzes the relationship between mid-sized blockholders and firm risk. We show that ownership structure matters for firm risk beyond the first largest blockholder. Firms with multiple blockholders take more risk than firms with just one blockholder, even when controlling for the stake...

We study mix-and-match compatibility choices of firms selling complementary products in a dynamic setting. Contrary to what happens in a static setting where symmetric firms choose compatibility (Matutes and Regibeau 1988), when switching costs are high and firms make price discrimination based on...

In the framework of spatial econometric interaction models for origin-destination flows, we develop an estimation method for the case when the list of origins may be distinct from the list of destinations, and when the origin-destination matrix may be sparse. The proposed model resembles a...

This paper studies the impact of corporate political influence on fiscal policy. We in-troduce different interest groups, firms and households, into a simple growth model with incomplete markets and heterogeneous agents. Firms face non-insurable id-iosyncratic productivity shocks. They finance their...

Human adaptation relies on the multigenerational transmission and accumulation of both skills and knowledge. Nonetheless, there is currently no agreement on which factor, or combination of factors, explains our peculiar ability to do so. Theoretical and empirical work, however, has identified many...

In econometrics, the impact of climate change on agricultural yield has often been modeled using linear functional regression, where crop yield, a scalar response, is regressed on the temperature distribution over a given time period, treated as an ordinary functional parameter, along with other...

We study the optimal design of social long-term care (LTC) insurance when the utility of informal caregivers is taken into account. Informal care is exchange-based. Children’s cost of providing care is continuously distributed over some interval and is not observable. Parents choose a rule...
