The impact of endogenous tax treaties on foreign direct investment: theory and evidence

Abstract .  This paper investigates the effect of tax treaties on bilateral stocks of outward FDI. For this purpose we employ a numerically solvable general equilibrium model of trade and multinational firms to study the impact of tax treaties on both welfare and outward FDI. The model indicates under which factor endowment configurations countries gain in welfare when implementing a tax treaty. This motivates an empirical specification of the endogenous selection into implementing new tax treaties. Using data of bilateral OECD outward FDI between 1985 and 2000, we find a significant negative impact of newly implemented tax treaties on outward FDI stocks.     

The unbearable tightness of being in a monetary union: Fiscal restrictions and regional stability

We study how constrained fiscal policy can affect macroeconomic stability and welfare in a two-region model of a monetary union with sticky prices and distortionary taxation. Both government spending and taxes can be used to stabilize regional variables; however, the best welfare outcome is obtained under some tax variability and constant regional inflations. We use a variety of rules to characterize constrained fiscal policy and find that strict fiscal rules coupled with a monetary policy that targets union-wide inflation result in regional inflation stability and the welfare costs of such rules are not as unbearable as one would expect. Fiscal authorities can enhance welfare by targeting the regional output gap, while targeting regional inflation is less successful since inflation stability is guaranteed by the central bank.     

An equilibrium analysis of information aggregation and fluctuations in markets with discrete decisions

This paper shows how the interaction between decentralized information gathering and discreteness of investment decisions at the individual level can generate random fluctuations in aggregate investment that involve occasionally large allocation errors. This interaction is illustrated in a model in which private information is costly to acquire and prices reveal information. The unique rational expectations equilibrium outcome of the model is shown to always be noisy and characterized by investment levels which may be high simply because uninformed investors are buying under the impression that the high price is a signal of good investment opportunities.     

Productivity,earnings, and profit sharing — An econometric analysis of alternative models

The theoretical status of the relationship between productivity, wages, and profit sharing (PS) is poor. Only some alternative hypotheses can be formulated. From these explanations six different econometric models are derived. Using data of the German Socio-Economic Panel the models are estimated and tests and indicators are employed to choose the best model. Our investigation speaks in favour of hybrid simultaneous Tobit models where the level of profit sharing is positively correlated with productivity which induces positive wage effects on the one hand. But on the other hand the level of wages is also relevant to the question whether a firm introduces or decides to continuePS and which amount ofPS should be paid.What is obvious is not always true and introspection is a notoriously unreliable guide to empirical magnitudes.

Evaluating the performance of the search and matching model

Does the search and matching model fit aggregate U.S. labor market data? While the model has become an important tool of macroeconomic analysis, recent literature pointed to some significant failures in accounting for the data. This paper aims to answer two questions: (i) Does the model fit the data, and, if so, on what dimensions? (ii) Does the data “fit” the model, i.e. what are the data which are relevant to be explained by the model?The analysis shows that the model fits certain specifications of the data on many dimensions, though not on all. This includes capturing the high persistence and high volatility of most of the key variables, the negative co-variation of unemployment and vacancies, and the behavior of the worker job finding rate. A key role in this fit is played by the convexity of hiring costs and the stochastic properties of the separation rate. The latter is a major component of the rate discounting the future value of the job-worker match.The paper offers a workable, empirically grounded version of the model for the analysis of aggregate U.S. labor market dynamics.     

Modeling Cyclical Asymmetries in European Imports

This paper applies smooth transition models to capture the nonlinear behavior in the imports data of six major European economies and to assess whether such nonlinearities are related to business cycle asymmetries. Two classes of switch between regimes are considered: endogenously determined transition that assumes nonlinearities are generated by idiosyncratic components specific to foreign trade, and exogenous transition based on GDP growth as a more direct indicator of the cyclical state of the economy. The results support the proposition that the dynamics of imports are nonlinear. In Belgium, France, Spain, and the United Kingdom, regimes change over the business cycle, while in Germany and Italy the switch between regimes is endogenous. National characteristics play a role in defining the position of extreme regimes, the smoothness of the transition, and local dynamics within each state.Previous versions of this article have been presented at the 57th International Atlantic Economic Conference (Lisbon, Portugal, March 10–14, 2004) and at the VII Encuentro de Economía Aplicada (Vigo, Spain, June 3–5, 2004).

Will the (German) NAIRU Please Stand Up?

Abstract. This paper deals with a critical assessment of the ‘non‐accelerating inflation rate of unemployment’ (NAIRU) for Germany. There are quite a few obstacles to perceiving the NAIRU as an easy‐to‐use analytical instrument: the possibility of a non‐vertical Phillips curve, the occurrence of shocks and hysteresis effects, and the (mis‐)measurement of important variables, cointegration issues and a time variability of the NAIRU. A new attempt is made to estimate a NAIRU for Germany using direct measures of inflationary expectations. However, by any method, the NAIRU is very hard to determine and subject to considerable arbitrariness.     

Inflation and Relative Price Variability in a Low Inflation Country: Empirical Evidence for Germany

Abstract. The recent literature on the welfare cost of inflation emphasizes inflation's effect on the variability of relative prices. Expected and unexpected inflation have both been proposed to increase relative price variability (RPV) and, thereby, to distort the information content of nominal prices. This paper presents new evidence on the impact of inflation on RPV in Germany. Our results indicate that the influence of expected inflation disappears if a credible monetary policy stabilizes inflationary expectations on a low level. Yet the significant impact of unexpected inflation suggests that even low inflation rates can lead to welfare losses by raising RPV above its efficient level.     

Delays and equilibria with large and small information in social learning

The general model of social learning with irreversible investment and endogenous timing is analyzed for any distribution of private informations. Strategic complementarities and multiple equilibria appear which are generated solely by information externalities. Different equilibria generate strikingly different amounts of information. The impacts of various assumptions (bounded beliefs, large number of agents, discrete time and short periods) are examined carefully. The properties are robust to the introduction of observation noise with a continuum of agents.
