Regulatory Protection And The Role Of International Cooperation, Yuan Mei
Regulatory Protection And The Role Of International Cooperation, Yuan Mei
Research Collection School Of Economics
I develop a general equilibrium framework to analyze the welfare consequences of product regulations and their international harmonization. In my model, raising product standards reduces a negative consumption externality, but also increases the marginal and fixed costs of production. When product standards are set noncooperatively, the effects of standards on other countries' wages and number of firms are not internalized, giving rise to an international inefficiency. The World Trade Organization's nondiscrimination principle of national treatment only partly addresses this inefficiency. Welfare losses from abandoning national treatment average 2.8%, whereas the maximum welfare gains from efficient cooperation average 11.8%.

An influential hypothesis states that export pioneers are too few relative to social optimum because the first exporter's action creates an informational public good for all subsequent exporters. The hypothesis has been invoked to justify certain types of government interventions. We note, however, that such market failure requires two inequalities to hold simultaneously: the discovery cost is neither too low nor too high. Neither has to hold in the data. We propose a structural estimation framework to evaluate the hypothesis, and estimate the parameters based on the customs data of Chinese electronics exports. Our key finding is that "missing pioneers" …
Firm Productivity And The Variety Of Inputs And Outputs: Evidence From Chinese Trade Data, Ken Onishi, Jianhuan Xu, Guang Yang
Firm Productivity And The Variety Of Inputs And Outputs: Evidence From Chinese Trade Data, Ken Onishi, Jianhuan Xu, Guang Yang

This paper studies how the trade liberalization in China changes the firm productivity. We develop a framework to estimate revenue productivity (TFPR) and real productivity (TFPQ) with multi-product firms. We find that the aggregate TFPR increases 30\% from 2002-2007 and TFPQ increases 22\%, suggesting that the observed TFPR increase is mainly driven by real productivity change rather than the markup change. We further decompose the change of productivity into three channels: (1) access to foreign inputs; (2) technology upgrade; (3) resource re-allocation within the firm. We find the most significant channel is the last one, which explains half of the …
Between Lives And Economy: Optimal Covid-19 Containment Policy In Open Economies, Wen-Tai Hsu, Hsuan-Chih Luke Lin, Yang Han
Between Lives And Economy: Optimal Covid-19 Containment Policy In Open Economies, Wen-Tai Hsu, Hsuan-Chih Luke Lin, Yang Han
Research Collection School Of Economics
This paper studies optimal containment policy for combating a pandemic in an open-economy context. It does so via quantitative analyses using a model that incorporates a standard epidemiological compartmental model in a multi-country, multi-sector Ricardian model of international trade with full-fledged input-output linkages. We devise a novel approach in computing optimal national policies in the long run, and contrast these policies with a baseline in which countries maintain their current policies until vaccine availability. The welfare gains under optimal policies are asymmetric as the gains for the set of countries which should tighten up the containment measures are much larger …
Globalization And Top Income Shares, Lin Ma, Dimitrije Ruzic
Globalization And Top Income Shares, Lin Ma, Dimitrije Ruzic
Research Collection School Of Economics
This paper documents empirically that access to global markets is associated with a higher executive-to-worker pay ratio within the firm. It then uses China's 2001 accession to the World Trade Organization as a trade shock to show that firms that exported to China prior to 2001 subsequently exported more, grew larger, and grew more unequal in terms of executive-to-worker pay. To evaluate analytically and quantitatively the impacts of globalization on top income inequality, this paper builds a model with heterogeneous firms, occupational choice, and executive compensation. In the model, executive compensation grows with the size of the firm, while the …
Energy Price Shocks And External Balances, Bao Tan Huynh
Energy Price Shocks And External Balances, Bao Tan Huynh
Research Collection School Of Economics
This paper studies the impact of a wide set of energy price shocks on exter- nal balances using a two-country framework comprising multiple sectors and en- dogenous energy production with convex costs. The paper disentangles different demand and supply shocks in the energy market through their distinct impact on external balances. It provides a theoretical confirmation of Kilian et al. (2009) and a theoretical foundation to the determining role of the non-energy trade balance in the transmission of energy price shocks. The presence of durables also highlights the immediate channel through which energy prices impact the non-energy trade balance.
