Abstract:
Over the last decade, quantifying the welfare effects from tariff changes has become one of the main challenges among international trade economists. There are a number of quantitative trade models with micro-foundations which emphasize demand-side (Anderson and Van Wincoop 2003), supply-side (Eaton and Kortum 2002), Bertrand competition (Bernard et al. 2003), extensive and intensive margin (Chaney 2008), etc, and conclude that trade liberalization with tariff reductions leads an economy to reach a higher level of welfare compared to pre-liberalization (Costinot and Rodriguez-Clare 2014). While elegant, these models inducing gravity equations share the common assumption, a perfect labor market. Quantitative trade models with full-employment developed so far have not taken account of labor market frictions when evaluating the welfare effects from tariff changes. This paper aims to fill the gap in the trade literature by explicitly considering labor market frictions. I employ search-and-matching to a multi-country and multi-sector Ricardian model with input-output linkages, trade in intermediate goods, and sectoral heterogeneity, in order to quantify the welfare effects from tariff changes. The paper shows that labor market frictions can be a source of comparative advantage in the sense that better labor market conditions contribute to lower cost in production. Labor market frictions play a critical role in determining the probability of exporting goods to trading partners, and interact with bilateral trade share, price, expenditures, etc. Unemployment and changes in unemployment rates due to tariff reductions contribute welfare changes across countries, implying that welfare effects based on quantitative trade models with full-employment are likely to be biased. I confirm the biased welfare effects by revisiting Caliendo and Parro (2015), who conduct an analysis of the welfare effects from the NAFTA from 1993 to 2005. I show that the welfare gap between theirs and mine has a positive correlation with changes in observed unemployment rates across countries. With the constructed model, I further conduct counterfactual exercises by asking what would happen if China’s tariffs remain unchanged from 2006 to 2015. It turns out that there are mild welfare effects to trading partners in the world trading system.

22. Ecommerce and Firm Performance: Evidence from Korea

Abstract:
Official estimates peg global business-to-business ecommerce at 15 trillion dollars and global business-to-consumer ecommerce at 1.2 trillion dollars in 2013 (UNCTAD 2015). When we turn to official estimates for Korea, it is easy to find that Korea’s business-to-consumer ecommerce market is grow-ing at more than twenty percent per year and has emerged as the third larg-est global ecommerce market in Asia. It is not very much surprising to know the numbers for Korea since Korea is one of the world’s most ad-vanced countries in terms of information and communication technology. However, it is somewhat surprising that we know little about how ecom-merce firms or establishments are distributed in the economy of Korea. In addition, we know little about how ecommerce establishments perform relative to their counterparts of a similar age and size in the same industry. The paper aims to characterize and test performance differences between ecommerce and non-ecommerce firms or establishments. Although the number of ecommerce establishments makes up a small fraction of the economy, ecommerce establishments have a heavier weight in sales, em-ployment, and wage. Due to endogeneity of ecommerce variable, the paper reconstructs the 2010 Korea Census dataset by using Propensity Matching Score and shows that in manufacture ecommerce establishments have, on average, larger sales-per-worker and pay higher wage whereas in services ecommerce ones have higher sales-per-worker but pay no larger wage than their counterparts of a similar age and size in the same industry. It also adds quantile estimates showing that sales-per-worker differences between ecommerce and non-ecommerce establishments in manufacture are positive and statistically significant only at lower quantiles of the distribution. In ser-vices, sales-per-worker differences between them are positive and signifi-cant at most of distribution but turns to be negative, though not significant, at above upper quantile of the distribution.

23. Getting tough with the dragon? The comparative correlates of foreign policy attitudes toward China in the United States and UK

Abstract:
A large body of research suggests mass publics are capable of thinking coherently about international relations. We extend this body of research to show that domain relevant postures – in our case, more abstract beliefs about foreign policy – are related to how tough of a line representative samples of US and UK respondents want their governments to take toward China. More specifically, we utilize a unique comparative survey of American and British foreign policy attitudes to show broad support for toughness toward China. Beliefs about the use of the military and attitudes regarding globalization help explain preferences for tough economic and military policies toward China. In the two countries, the relationship between general foreign policy outlooks and the positions citizens take is robust to the addition of a general mediator that controls for the general affect those surveyed have toward China. Finally, the strength of the relationship between these abstract postures and specific preferences for a China policy are different across the countries.

24. Will Europe Fall into a Japanese-Style Stagnation Trap?

Abstract:
Can Europe avoid falling in to a Japanese-style stagnation trap? In this type of trap, we see a repeated cycle of a financial crisis leading to a fiscal crisis, leading to a decline in consumer and investor confidence, and a resulting fall in demand. The decline in growth that inevitably follows simply causes the cycle to repeat itself. In theory, this should lead to improved competitiveness, but in Japan the forces of decline outweighed any boost in export demand. This E-brief is based on Peter Harrold’s presentation at the CASE 2011 International Conference on "Europe 2000: Exploring the Future of European Integration" held on November 18-19, 2011.
