R&D INTENSITY AND THE EFFECTIVE TAX RATE: A META-REGRESSION ANALYSIS

We apply meta-regression techniques to provide a quantitative review of the empirical literature on how research and development (R&D) expenses affect the effective tax rate (ETR). R&D expenses relate to a well-accepted profit shifting channel, strategic placement of intellectual property within a multinational entity. Using a unique hand-collected data set, we add a new perspective to the current base erosion and profit shifting (BEPS) state of research and debate, in three ways: First, observing that primary studies report mixed evidence on how R&D expenses affect ETR, we provide a consensus estimate for this effect. Second, we consider this effect in more detail by separating a tax accounting effect and a profit shifting effect, which to our knowledge has not yet been investigated. We detect that one-third of the R&D effect on the ETR is due to the tax accounting effect and could be mitigated via book-tax conformity. We further find that 10% of the profit shifting effect can be traced back to R&D tax credits. Third, our meta-regression reveals factors that are possible sources of variation and bias in previous empirical studies.     

REAL EXCHANGE RATE CYCLES AROUND ELECTIONS

We develop the implications of devaluation cycles for real exchange rates in a two-sector small open economy with a cash-in-advance constraint. Policy-makers are office-motivated politicians. Voters have incomplete information on the competence and the opportunism of incumbents. Devaluation acts like a tax, and is politically costly because it can signal the government is incompetent. This provides incumbents an incentive to postpone devaluations, and can lead to an overvalued exchange rate before elections. We compare the implied cycle of appreciated/depreciated exchange rates with empirical evidence around elections from Latin America.     

The choice of exchange rate regime: An empirical analysis for transition economies*

We analyze the choice of exchange rate regimes of the 25 transition economies in Europe and the CIS after 1990. The empirical results show that the traditional Optimum Currency Area considerations provide relevant guidance for the regime choices in these countries. Moreover, regime choices are influenced by inflation rates, cumulative inflation differentials, and international reserves sufficiency. That is, macroeconomic stabilization and the ability to commit to exchange rate pegs also play important roles. Large government deficits have ambiguous effects; they increase the likelihood of moving from flexible to intermediate regimes as well as that of moving from fixed to intermediate ones.     

Buying Influence: Aid Fungibility in a Strategic Perspective

I study equilibria of non‐cooperative games between an aid donor and a recipient when there is conflict over the allocation of their combined budgets. The general conclusion is that a donor's influence over outcomes is increasing in the share of the available resources it controls; if this share is large enough, aid fungibility is not important as the donor achieves its most preferred allocation. The game‐theoretic approach to fungibility is contrasted with the traditional non‐strategic approach. I argue that the former is superior as it derives final allocations instead of assuming them, making analysis of the sources of influence over outcomes possible.     

Central Bank Policy in a More Perfect Financial System

Financial innovation increases markets' liquidity and provides economic agents with new instruments to better handle risks, but it reduces the efficacy of monetary policy while strengthening the logic and force of the “unholy trinity”. Increased liquidity of financial markets and increased leverage of financial positions imply that speculators can attack unsustainable fixed exchange rates faster and more powerfully than ever. The rapid innovation of new financial instruments in these markets also implies the futility to “throw sand in the wheels” through regulation or the introduction of transaction taxes. The higher asset substitutability generated by the emergence of derivatives makes the definition of “money,” particularly of broad monetary aggregates, increasingly difficult. In a more complete financial market system central banks find it harder to predict the effect of a given monetary impulse on real output and employment with any reasonable precision. Discretionary monetary policies aimed at output and employment become more uncertain. Consequently, central banks should focus on the long-run goal of price stability.
