Assessing aggregate reallocation effects with heterogeneous inputs,and evidence across countries

Theoretically, reallocating an input from a firm where the input has low marginal product to a firm where the input has high marginal product would increase aggregate productivity without any underlying change in technology. This paper argues that measuring these reallocation effects requires accounting for detailed input types because, for example, differences in wages across producers often reflect the skill mix of workers, not allocative inefficiency. The paper develops an approach to measuring reallocation that accounts for worker skill and the composition of capital assets, thus focuses on the set of countries for which this information is available. The results show once input heterogeneity is accounted for, the effects of reallocation on aggregate productivity were small on average, but sizable in a subset of countries. Panel regressions indicate that reallocation effects are related to population distribution and government effectiveness.     

Export survival and the dynamics of experience

This paper focuses on developing countries’ pioneer exports to the OECD and obtains several important results on export dynamics, linking export experience and export survival. Using product level data at the SITC 5-digit level for 114 developing countries over the 1962–2009 period, we show that prior export experience obtained in non-OECD markets significantly increases survival of pioneer exports toward the OECD. The experience does not need to last long, as gaining experience for more than two years does not confer any additional benefit. The effect of experience depreciates rapidly with time: a break in export experience prior to entering the OECD reduces the advantage on survival. Finally, the role of prior export experience is particularly relevant for survival in the first two years upon entry into the OECD. The geographic dynamic of export experience reveals that experience is acquired in neighboring, easy to access markets before reaching more distant, richer partners and ultimately serving the OECD with a higher probability of survival.     

Optimal Exchange-Rate Policy in a Model of Local-Currency Pricing with Vertical Production and Trade

In this paper, we examine optimal exchange-rate flexibility in a model of local-currency pricing with vertical production and trade. Following a large body of empirical evidence, we assume that final-goods prices are sticky, but intermediate-goods prices are flexible. We find that, unlike what is found in the literature, optimal nominal exchange rate is flexible under local-currency pricing. The key element in deriving our conclusion is the difference in expenditure shares between home and foreign households. The conclusion holds even if the degrees of home bias in production are identical between home and foreign final-goods producers, which contrasts with the findings in the literature.     

The London Monetary and Economic Conference of 1933 and the End of the Great Depression

In this paper I analyze the London Monetary and Economic Conference of 1933, an almost forgotten episode in U.S. monetary history. I study how the Conference shaped dollar policy during the second half of 1933 and early 1934. I use daily data to investigate the way in which the Conference and related policies associated to the gold standard affected commodity prices, bond prices, and the stock market. My results show that the Conference itself did not impact commodity prices or the stock market. However, it had a small effect on bond prices. I do find that the events associated with the abandonment of the gold standard impacted prices in a significant way, even before the actual monetary and currency channels were at work. These results are consistent with the “change in regime” hypothesis of Sargent (1983).     

Direct and Spillover Effects of Unconventional Monetary and Exchange Rate Policies

This paper explores the direct effects and spillovers of unconventional monetary and exchange rate policies. We find that official purchases of foreign assets have a large positive effect on a country’s current account that diminishes considerably as capital mobility rises. There is an important additional effect through the lagged stock of official assets. Official purchases of domestic assets, or quantitative easing (QE), appear to have no significant effect on a country’s current account when capital mobility is high, but there is a modest positive impact when capital mobility is low. The effects of purchases of foreign assets spill over to other countries in proportion to their degree of international financial integration. We also find that increases in US bond yields are associated with increases in foreign bond yields and in stock prices, as well as with depreciations of foreign currencies, but that all of these effects are smaller on days of US unconventional monetary policy announcements. We develop a theoretical model that is broadly consistent with our empirical results and that highlights the potential usefulness of domestic unconventional policies as responses to the effects of foreign policies of a similar type.     

Business Cycle Synchronization in the EMU: Core vs. Periphery

This paper examines business cycle synchronization in the European Monetary Union with a special focus on the core-periphery pattern in the aftermath of the crisis. Using a quarterly index for business cycle synchronization by Cerqueira (Int Econ Econ Policy 10(3):349–363, 2013), our panel data estimates suggest that it is countries belonging to the core that are faced with increased synchronization among themselves after 2007Q4, whereas peripheral countries decreased synchronization with regards to the core, non-EMU countries and among themselves. Correlation coefficients and nonparametric local polynomial regressions corroborate these findings. The usual focus on co-movements and correlations might be misleading, however, since we also find large differences in the amplitude of national cycles. A strong common cycle can thus lead to large differences in cyclical positions even if national cycles are strongly correlated.     

The Economic Impact of Brexit: Evidence from Modelling Free Trade Agreements

This paper assesses the economic implications of the United Kingdom (UK) leaving the European Union (EU). The basic data on trade in goods and services and investment between the two parties suggest that the cost of “Brexit” could be substantial. Trade between the UK and the EU-27 is large and of a similar order of magnitude as transatlantic trade (between the EU and the U.S.). The precise nature of the (hopefully free) trade agreement UK-EU-27 is still being negotiated. All available studies concur that a significant disruption of trade links will impose economic costs on both sides. However, the EU-27 would bear only a disproportionally small share of the total cost, not just because it is about five times larger than the UK in economic terms, but also for fundamental reasons such as greater market power of its enterprises. Other studies on different free trade arrangements confirm the general proposition that the smaller party has more to gain from eliminating trade barriers (and more to lose from imposing them). This implies that the EU will have a stronger negotiating position.
