Currency Invoicing in International Trade: an Empirical Investigation

The authors investigate the choice of currency of invoicing in international trade under exchange rate fluctuations. Predictions derived from a model developed by Donnenfeld and Zilcha in 1991, and others, regarding the optimal choice of currency of invoice are tested for imports into Canada. The authors employ a unique dataset from Customs Canada that covers a six-year period and lists all currencies used for invoicing by industry. The empirical results support the hypothesis that there is a positive relationship between the extent of invoicing in the importer's national currency and exchange rate risk, and a negative relationship between invoicing in the exporter's currency as well as invoicing in a third currency and exchange rate risk. The empirical results further indicate that relative size of a country plays a role in determining the currency of invoicing.

The Impact of Accounting Earnings Disclosures on Stock Prices in Singapore

This paper reports the relationship between earnings and share prices. The results show that unexpected earnings changes are significantly associated with share price changes. However, the strength of the earnings effect is not as pronounced as those reported in the more analytically-intensive developed stock markets. The results are adjusted for risk differences by using a non-synchronous correction procedure to remove thin-trading bias.     

Monetary policy in the euro area: Was it too tight in the 1990s?

This paper studies the monetary policy in the euro area. An important question concerning the euro area is whether the monetary policy has been too tight in the 1990s and in turn, caused the high unemployment rates, in contrast to the economic prosperity and low unemployment rate of the U.S. Therefore, the authors explore what would have happened to the euro economy if the Central Banks had followed either the fixed or time-varying monetary policy rule of the U.S. The paper does find that the European central banks and then later the ECB overreacted to past inflation pressures.     

Price stability through price-level targeting or inflation targeting? A tale of two experiments

Price stability can be attained through price-level or inflation targeting. This paper compares the two monetary policy strategies from both a historical and a theoretical perspective. The Swedish experiment with price-level targeting in the 1930 occurred within a framework that lacked the accountability characteristic of New Zealand's current policy framework for inflation-targeting. Using a simple forward-looking rational expectations framework, we show that price-level targeting offers a better output-inflation variability tradeoff than inflation targeting in the forward-looking New Keynesian framework.     

Information structure and stochastic control performance

The linear quadratic control problem with unknown parameters is analytically intractable. To obtain an analytically tractable strategy the statistical assumptions frequently considered are (1) fixed known parameters, (2) independent random parameters, and (3) independent path dependent stochastic parameters. Also considered are three information structures — (1) no observations, (2) observations without anticipation, and (3) observations with anticipation. Treating the assumptions as true, the performance of the strategies is shown to monotonically improve with respect to the information structure in order 1, 2, 3 and with respect to the statistical assumptions in order 2, 3, 1. The results provide estimates of the performance losses due to position and parameter uncertainty for the unknown parameter case.     

UNEMPLOYMENT,LABOR MARKET TRANSITIONS,AND RESIDUAL WAGE DISPERSION

It is commonplace in the debate on Germany's labor market problems to argue that low wage dispersion is a major reason for the high unemployment rate. This paper analyzes the relationship between unemployment and residual wage dispersion for individuals with comparable attributes. In the conventional neoclassical point of view, wages are determined by the marginal product of the workers. Accordingly, increases in union minimum wages result in a decline of residual wage dispersion and higher unemployment. A competing view regards wage dispersion as the outcome of search frictions and the associated monopsony power of the firms. Accordingly, an increase in search frictions causes both higher unemployment and higher wage dispersion. The empirical analysis attempts to discriminate between the two hypotheses for West Germany analyzing the relationship between wage dispersion and both the level of unemployment as well as the transition rates between different labor market states. The findings are not completely consistent with either theory. However, as predicted by search theory, one robust result is that unemployment by cells is not negatively correlated with the within‐cell wage dispersion.     

On discretion versus commitment and the role of the direct exchange rate channel in a forward-looking open economy model

Abstract

This paper compares optimal monetary policy under discretion and commitment in an economy where the direct exchange rate channel is operative. The stabilization bias under discretion is shown to be weaker in an open economy relative to a closed economy. In an open economy, a ‘less conservative central banker’, one that attaches a smaller weight to the variance of inflation in the loss function, can be appointed to replicate the behaviour of real output that eventuates under commitment. Evaluating the social loss function under discretion and commitment, we find that the existence of a direct exchange rate channel in the Phillips Curve mitigates the pronounced differences between the two strategies in case of high persistence in the stochastic shocks.
