Trade deficits aren’t as bad as you think

Although the amount of U.S. imports and exports has varied greatly over time, in recent years, the U.S. has been running trade deficits. Some people react to such trade deficits with doom and gloom; others cite them as evidence that foreign governments are not playing fair in U.S. markets; still others argue that deficits demonstrate that we are living beyond our means. In “Trade Deficits Aren’t as Bad as You Think,” George Alessandria offers an alternative view: Trade deficits have benefits. They shift worldwide production to its most productive locations, and they allow individuals to smooth out their consumption over the business cycle.Trade

Supersymmetric noncommutative solitons

I consider a supersymmetric Bogomolny-type model in 2+1 dimensions originating from topological string theory. By a gauge fixing this model is reduced to a supersymmetric U(n) chiral model with a Wess-Zumino-Witten-type term in 2+1 dimensions. After a noncommutative extension of the model, I employ the dressing method to construct explicit multi-soliton configurations on noncommutative R^{2,1|2N}.Comment: 13 pages, 2 figures; talk given during "Noncommutative Spacetime Geometries" at Alessandria, March 2007, and "Noncommutative Geometry and Physics" at Orsay, April 200

Trade and the (Dis)Incentive to Reform Labor Markets: The Case of Reform in the European Union

In a closed economy general equilibrium model, Hopenhayn and Rogerson (1993) find large welfare gains to removing firing restrictions. We explore the extent to which international trade alters this result. When economies trade, labor market policies in one country spill over to other countries through their effect on the terms of trade. A key finding in the open economy is that the share of the welfare gains from domestic labor market reform exported substantially exceeds the share of goods exported. In our baseline case, 105 percent of the welfare gains are exported even though the domestic economy only exports 30 percent of its goods. Thus, with international trade a country receives little to no benefit, and possibly even loses, from unilaterally reforming its labor market. A coordinated elimination of firing taxes yields considerable benefits. We find the welfare gains to the U.K. from labor market reform by its continental trading partners of 0.21 percent of steady state consumption. This insight provides some explanation for recent efforts toward labor market reform in the European Union.Firing Costs, International Trade, Labor Market Reform

Why are goods so cheap in some countries?

Looking around the world, we observe substantial differences across countries in prices for most goods. These price differences also tend to be positively correlated with income differences, so that citizens of high-income countries tend to pay more for the same goods than citizens in low-income countries. In “Why Are Goods So Cheap in Some Countries?,” George Alessandria and Joseph Kaboski summarize some of the evidence related to the big price differences across countries for a broad set of goods. They then discuss the relationship between prices and income levels and some possible explanations for that relationship.Prices

Anomalous U(1)'s, Chern-Simons couplings and the Standard Model

This proceeding is based on hep-th/0605225 and it shows that the most general anomaly related effective action contains Stuckelberg, axionic and Chern-Simons-like couplings. Such couplings are generically non-trivial in orientifold string vacua. A similar analysis in quantum field theories provides similar couplings. These Chern-Simons couplings generate new signals which might be visible at LHC.Comment: 9 pages, 2 eps figures, LaTeX, feynmf & youngtab packages. (v2: references added).

Do sunk costs of exporting matter for net export dynamics?

Not all firms export every period. Firms enter and exit foreign markets. Previous research has suggested that these export participation decisions have significant aggregate implications. In particular, it has been argued that these export decisions are important for the comovements of net exports and the real exchange rate. In this paper, the authors evaluate these predictions in a general equilibrium environment. Specifically, assuming that firms face an up-front, sunk cost of entering foreign markets and a smaller period-by-period continuation cost, they derive the discrete entry and exit decisions yielding exporter dynamics in an otherwise standard equilibrium open economy business cycle model. The authors show that the export decisions of firms in the model are influenced by the business cycle in a manner consistent with evidence presented for U.S. exporters. However, in contrast to previous partial equilibrium analyses, model results reveal that the aggregate effects of these export decisions are negligible.Exports ; Foreign exchange rates
