Likelihood Regions: An Axiomatic Approach
écrit avec Fan Wang and Stefania Minardi
We consider a reasoner who selects a set of distributions given a database of observations. A likelihood region is monotonic with respect to the likelihood function. We provide axiomatic foundations for such a selection rule. Starting with an abstract set of theories, we propose conditions on choice functions (across different databases) for which there exists a statistical model such that the choice function is a likelihood region relative to that model, for the general case and for the case of a fixed likelihood-ratio threshold. We interpret the results as supporting the notion of likelihood regions for the selection of theories.

One bed, two dreams: Female migration, conservative norms and foreign brides in South Korea
Migration affects a country’s social and demographic outcomes, such as marriage and fertility. However, the effects of internal migration on family formation are still not well documented. In this paper, I study how internal migration affects the marriage market and fertility rates. In particular, I use the setting of South Korea to analyze how female internal mobility affects the demand for marriages between local men and immigrant brides. I then investigate the implications of both female internal mobility and foreign brides for fertility rates. To obtain causal identification, I estimate these effects using a two-way fixed effect model and an enclave instrument based on past internal migration. I find that an increase in out-migration of local women raises the demand for immigrant brides, particularly in rural areas. I also find a negative effect of female out-migration on fertility, which is partially offset by the arrival of foreign brides. Further, I demonstrate that the gap in gender attitudes between younger generations of Korean men and women in part explains both female internal mobility and the demand for foreign brides. I empirically show that the "import" of brides from different countries is the response to a marriage squeeze brought by female internal migration.

* Incentive-Based Pay and Building Decarbonization: Experimental Evidence from the Weatherization Assistance Program
Abstract: Building energy efficiency is a cornerstone of greenhouse gas mitigation strategies with billions of dollars set aside for extensive upgrades in the coming years. However, impact evaluations have revealed actual energy savings from home upgrade programs often fall short of projections, in part due to contractor underperformance. Using field experiment results, we show refining one program design element—offering performance bonuses to contractors--increased natural gas savings by 24% and generated $5.39-$14.53 in social benefits per dollar invested. Hence, how money is allocated within government programs may be as important as choosing among programs for maximizing returns to public spending
