Why is it so Difficult to Find an Effect of Exchange Rate Risk on Trade?

It is commonly argued that exchange rate risk depresses international trade. However, the large literature on this subject has not yet provided conclusive evidence. This paper analyzes why it is so difficult to obtain a clear answer from time series analyses. We use data on bilateral aggregate U.S. exports to the other G7 countries. The results show that export decisions are mostly affected by the exchange rate about one year later. The riskiness of the exchange rate at such a long horizon appears fairly constant over time with only short-term fluctuations. This makes it difficult to discover the true effect of exchange risk on trade from the limited time series data that are typically available.

Trade Spillovers of Fiscal Policy in the European Union: A Panel Analysis

We explore the international spillovers from fiscal policy shocks via trade in Europe. A fiscal expansion stimulates domestic activity, which leads to more foreign exports and, hence, higher foreign output. To quantify this, we combine a panel VAR model in government spending, net taxes and GDP with a panel trade model. On average, a public spending increase equal to 1% of GDP implies 2.3% more foreign exports over the first two years. The corresponding figure for an equal-size net tax reduction is 0.6%. Both estimates are statistically significant. As far as the effect on foreign activity is concerned, a 1% of GDP spending increase (net tax reduction) in Germany on average raises GDP of trading partners by 0.23% (0.06%) over the first two years. These figures are likely to form lower bounds for the actual effects and suggest that it may be worthwhile to further investigate the benefits from coordinated fiscal expansions (contractions) in response to European-wide cyclical downturns (upswings).trade policy

Defending Against Speculative Attacks

While virtually all currency crisismodels recognise that the fate of a currency peg depends on how tenaciously policy makers defend it, they seldom model how this is done. We incorporate themechanics of speculation and the interest rate defence against it in the model ofMorris and Shin (American Economic Review 88, 1998). Our model captures that the interest rate defence reduces speculators’ profits and thus postpones the crisis. It predicts that well before the fall of a currency interest rates are increased to offset the buildup of exchange market pressure, and this then unravels in a sharp depreciation. This pattern is at odds with predictions of standard models, but we show that it fits well with reality.Exchange Market Pressure, Currency Crisis, Interest Rate Defence, Global Game

The efficiency of top agents: An analysis through service strategy in tennis

We consider the question whether top tennis players in a top tournament (Wimbledon) employ an optimal (efficient) service strategy. While we show that top players do not, in general, follow an optimal strategy, our principal result is that the estimated inefficiencies are not large: the inefficiency regarding winning a point on service is on average 1.1% for men and 2.0% for women, implying that–by adopting an efficient service strategy–players can (on average) increase the probability of winning a match by 2.4%-points for men and 3.2%-points for women. While the inefficiencies may seem small, the financial consequences for the efficient player at Wimbledon can be substantial: the expected paycheck could rise by 18.7% for men and even by 32.8% for women. We use these findings to shed some light on the question of whether economic agents are successful optimizers

How do governments respond to interest rates?

We explore the optimal and actual responses of fiscal policy to changes in the interest rate on newlyissued public debt (the “marginal interest rate”). We set up a simple theoretical framework with a government aiming to smooth public consumption over time. The distinctive feature is that the government issues debt of different maturities. This introduces a “valuation effect” that has received little attention so far: a rise in the marginal interest rate increases the rate of discounting and, thus, lowers the value of non-maturing debt, which relaxes the budget constraint, thereby inducing a fall in the primary balance. Still, the framework predicts that the total effect of a rise in the marginal interest rate is an increase in the primary balance. Estimates for developed countries suggest that a 1 percentagepoint higher marginal interest rate leads, on average, to roughly a 1 percentage-point higher primary balance. These findings are consistent with governments smoothing the impact of changes in the marginal interest rate and exploiting the valuation effect. Finally, estimates suggest a role for the average (or “effective”) interest rate on outstanding debt.info:eu-repo/semantics/publishedVersio
