李昊洋助教授的合作论文“Emission Pricing, Emission Rebound, and the Coverage Scope of Incomplete Regulations” (合作者为中央财经大学吴楠助教授) 被Journal of Environmental Economics and Management接受发表。


Abstract
This paper studies the emissions pricing of incomplete regulations when accurate firm-level information is unavailable. In an economy with monopolistically competitive heterogeneous firms, the equilibrium can be sufficiently characterized by an aggregate statistic, which we call the ‘‘coverage scope’’. Given the coverage scope, emissions leakage to the unregulated firms results in a ‘‘U-shaped’’ relationship between the aggregate emissions and emissions price. As the coverage scope expands, the second-best emissions price increases. Firm heterogeneity and market power, the two defining features of the monopolistically competitive economy, affect emissions pricing differently. While both of them affect the second-best emissions price indirectly through coverage scope, market power has an additional direct effect. As a result, the optimal emissions price does not always decrease in market power, which contrasts the traditional wisdom on emissions pricing under complete regulations. A multi-sector model is numerically simulated using parameters for five Chinese manufacturing sectors to be incorporated into a proposed national carbon emissions pricing program. Quantitatively, the second-best price varies substantially with coverage scope and market conditions.

蒋荷露助教授的合作论文“Skill-Biased Entrepreneurial Decline”(合作者为Faisal Sohail,墨尔本大学助理教授)被Review of Economic Dynamics接受发表。


Abstract
The U.S. is undergoing a long-term decline in entrepreneurship. We show that this slow-down in entrepreneurship has been more pronounced for skilled individuals – those with a college degree. We document new facts on the skill-biased nature of declining entrepreneurship and propose that it is a response to the rising worker skill premium observed over the same period. In support of this, we find that workers' earnings grew faster than entrepreneurs', particularly for skilled individuals, discouraging the pursuit of entrepreneurship. To quantify the impact of the skill premium on entrepreneurship, we develop a model of occupational choice with worker heterogeneity. In the model, a rising skill premium – driven by skill-biased technological change – contributes little in lowering entrepreneurship. Instead, around 70% of the observed decline in entrepreneurship is driven by skill-neutral technological change and a rising share of college graduates. A rise in the skill premium interacts with these forces to generate the skill-biased decline, and in doing so, shifts the composition of entrepreneurs towards the unskilled, lowering average entrepreneurial productivity. Our findings suggest an integral role for the changing income structure of workers in driving the broader decline in business dynamism in the U.S.

戴大荣助教授的合作论文“Voting over selfishly optimal income tax schedules with tax-driven migrations”(合作者为田国强教授)被Social Choice and Welfare在线发表。


Abstract
We study majority voting over selfishly optimal nonlinear income tax schedules proposed by a continuum of workers who can migrate between two competing jurisdictions. Both skill level and migration cost are the private information of each worker who will propose an allocation schedule that maximizes the utility of her own type. We identify reasonable scenarios in which the first-order approach applies and hence the second-order sufficient condition for incentive compatibility is fulfilled; otherwise, we need to apply the ironing surgery developed by Brett and Weymark (Games Econ Behav 101:172–188, 2017). Under quasilinear-in-consumption preferences, we show that the tax schedule proposed by the median skill type is the Condorcet winner, and provide a complete characterization of this tax schedule. While this schedule features negative marginal tax rates for low-skilled workers, it features positive rates for high-skilled workers with small migration elasticities; the marginal tax rates at the bottom and top skill levels cannot be unambiguously signed. Moreover, we detail the conditions under which migration induces uniformly higher or lower equilibrium marginal tax rates facing both low-and high-skilled workers than their counterparts in autarky, which leads us to conclude that geographic mobility does not always limit the government’s ability to redistribute incomes via tax-transfer systems.
