Greece’s Potential Trade Flows: A Gravity Model Approach

This paper attempts to access whether Greece’s low openness is a reflection of its low trade integration primarily as a result of the country’s relatively poor goods export performance. The analysis estimates potential trade flows for Greece through a gravity model using a panel of cross-country data, which cover bilateral trade flows concerning the EU member states. These flows are then derived by applying the estimated parameters to the Greek economy. The results show that actual Greek exports fall short of potential ones, while the opposite is true with respect to imports. This becomes more profound when the extent of intra-industry trade is included in the analysis. The findings for the Greek exports differ considerably from the corresponding ones for Portugal, a country with similar characteristics, manifesting the limited convergence of Greece’s trade patterns towards the EU average as well as its unique geographical location relatively to the other EU countries.

Structural breaks in Austrian foreign trade with Eastern Europe during the early 1970s

Between 1955 and 1987, Austrian trade with Eastern Europe was characterized by specific factors. On the one hand, trade flows were influenced by the central planning system in Eastern Europe. On the other hand, Austria applied non-standard policy tools to manage Eastern trade. Furthermore, Austrian trade with Eastern Europe was affected by the implementation of the free trade agreement with the European Communities (EC) and the change in the institutional framework for Eastern trade in the early 1970s. Austrian Eastern exports were fostered by increased export subsidies and barter trade. We assess the net effects of these contradictory measures of trade policy by estimating aggregate import and export equations and testing for a structural break in 1973. Our results are consistent with the view that Austria subsidized Eastern exports to pursue a countercyclical policy after 1973.

Export variety and the economic performance of countries

We explore the relationship between export variety and economic development, using data on OECD countries between 1964 and 2003. We show that structural change in the world economy has a particular arrow of time leading to a growing variety of exports. Distinguishing between related variety (within sectors) and unrelated variety (variety between sectors), we also show that related variety stimulates growth instantaneously, while unrelated variety only promotes growth with a considerable time lag. This finding is in line with the evolutionary notions that economic development and international trade patterns are path dependent.

Trade and productivity: an industry perspective

We use a sample of 14 OECD countries and 15 manufacturing industries to test for the effect of trade on productivity. Endogeneity concerns are accounted for using the geographical component of trade as instrument as suggested by Frankel and Romer (Am Econ Rev 89(3):279–399, 1999). We find that trade, measured in terms of the export ratio, increases productivity, even if country-fixed effects such as the quality of institutions are controlled for, though results are less robust for imports. Estimates at the aggregate manufacturing level turn out much larger, emphasizing the role of inter-industry spillovers.

Vertical Innovation and Catching-Up: Implications of EU Integration for CEECs-5

We analyze the role of vertical innovation in trade patterns for developing economies trading with technologically advanced countries. A model is presented where the international diffusion of knowledge, promoted by economic integration, is the source of a technological catching up and leads to a convergence in the quality of traded goods, with a positive effect on exports. We then turn our attention on the evolution of trade between the Central and Eastern European countries (CEECs-5) and their European Union partner countries, assessing whether economic integration has increase the quality of the goods produced. For the period 1995–2005, we find evidence of the increasing role of intra-industry trade and vertical differentiation and a process of specialization in higher quality products, especially in the medium- and high-skill sectors.

A simple note on herd behaviour

In his ‘Simple model of herd behaviour’, (Banerjee A (1992) A simple model of herd behaviour. Q J Econ CVII:797–817) shows that—in a sequential game—if the first two players have chosen the same action, player 3 and all subsequent players will ignore his/her own information and start a herd, an irreversible one. In this paper, we analyse the role played by the tie-breaking assumptions in reaching the equilibrium. We show that: players’ strategies are parameter dependent—an incorrect herd may be reversed; a correct herd is irreversible.

Price-setting behavior of Austrian firms

This paper explores nominal rigidities by investigating price-setting behavior of Austrian firms based on survey evidence. Distinguishing between two stages of price setting—first the price reviewing phase and second the price changing phase—our results suggest that the main obstacles to price flexibility lie on the second stage. Our main result is that firms postpone price adjustments, because they are afraid to antagonize customers with frequent price changes. Thus, customer relationships - especially those with consumers—are a major source of price stickiness in the Austrian economy.

The concept of choice: why and how innovative behaviour is not just stochastic

The goal of this paper is to highlight the importance of the concept of choice. To do so, a synopsis of the most important contributions to this topic—featuring an eclectic set of scholars across disciplines—is provided. As central to the argument, John von Neumann’s contributions, game theory and simulation techniques on von Neumann machines, are identified. Innovation (economic and theoretic) as the driving force behind human evolution seems to head for a new scientific paradigm based on von Neumann’s ideas.

Trade liberalization,intra-industry trade and the environment: competition mode and the order of firms’ moves

This paper explores the implications of trade liberalization by extending the intra-industry trade framework à la Fung and Maechler (J Int Trade Econ Dev 16(1):53–69, 2007) to the case of sequential move and taking the mode of firms’ competition into consideration as well. It is shown that the existing results obtained for the case of simultaneous price competition are robust in quantity competition and sequential move cases. Moreover, it studies the likelihood that the environmental effects of trade liberalization occur.

Mises’ democracy–dictatorship equivalence theorem: A critique

Ludwig von Mises argues that public opinion, not the form of government, is the ultimate determinant of policy. The implication is that, holding public opinion constant, democracies and dictatorships will have the same policies—a result I call Mises’ Democracy–Dictatorship Equivalence Theorem. According to Mises, dictators have to comply with public opinion or else they will be overthrown. I argue that he seriously overestimates the power of revolution to discipline dictators. Mises was perceptive to note that, in practice, “dictatorially imposed” policies are often democratically sustainable, but he neglected several mechanisms—all more plausible than the threat of revolution—capable of explaining this fact.

Changing of the guards: New coaches in Austria’s premier football league

Professional team sports provide an ideal real world experiment to explore the effect of top executive replacement due to the availability of excellent performance data. This paper investigates how replacing the coach affects the performance of football teams. Analyzing almost 2,000 matches of the Austrian premier football league by ordinal (probit) regression techniques we find that a new coach tends to enhance team performance in home matches but to weaken it in away matches. However, neither of these effects turns out to be statistically significant. Nevertheless, the much discussed coach effect—ousting an underperforming coach in order to improve team performance at least temporarily—may make sense despite the costs involved by providing stronger ex-ante incentives for effort.

Legal positivism and property rights: a critique of Hayek and Peczenik

Scholars such as Friedrich Hayek and Aleksander Peczenik have criticized legal positivism for undermining constitutionalism and the rule of law, an implication of which is weakened private property rights. This conclusion is far from evident. First, I contend that legal positivism is compatible with a strong support for property rights. Second, the causal relationship between legal positivism and the degree to which property rights are applied and protected is analyzed. The main arguments for a negative relationship—that legal positivism centralizes and politicizes legislation and that it makes the legal culture servile in relation to the political sphere—are considered unconvincing.

The rise and fall of monopolistic competition revolution

The widespread idea among economists is that monopolistic or imperfect competition is a set of realistic models that were invented in the 1930s and their purpose was to fill the gap between the polar and, at the same time, hypothetical models of perfect competition and pure monopoly. The main argument of this paper is that the monopolistic competition revolution set in motion a reaction—partly driven by methodological considerations, partly ideological—that ultimately led to the restoration of perfect competition, as the benchmark for evaluating market outcomes. In the end, monopolistic competition eclipsed, and perfect competition from the fridges of economic analysis that was up until the 1920s was placed to the very core of microeconomic model-building.

Transaction tax and stock market behavior: evidence from an emerging market

This study examines the impact of a stamp tax rate increase on market behavior, using data from two stock exchanges in China. We find that when the tax rate increases from 0.3 to 0.5% (which implies that the transaction cost increases by about 1/3) trading volume decreases by 1/3. This implies an elasticity of turnover with respect to a stamp tax of −50% and an elasticity of turnover with respect to transaction cost of −100%. The markets’ volatility significantly increases after the increase in the tax rate. Furthermore, the change in the volatility structure indicates that the markets become less efficient in the sense that shocks are less quickly assimilated in the markets.

Politics, selection and the public interest: Besley’s benevolent despot

This paper is an assessment of Besley’s attempt to orchestrate a rapprochement between public choice theory and conventional public economics—with its characteristic normative orientation towards public policy. In this paper, I first try to set the Besley enterprise in the context of earlier work—focussing on my own work with Buchanan (The Power to Tax and The Reason of Rules). I then direct attention to three aspects of the Besley enterprise: whether selecting for competence depends on having solved the motivation problem (either by incentive or selection means), how selection mechanisms might be supported institutionally and the possibility that selection processes might create incentives at the ‘dispositional’ level.

Does the Law of One Price Hold within the EU? A Panel Analysis

This paper empirically tests the law of one price by applying unit root tests to three panels consisting of data on 90 consumer price indices for the EU-25, the EU-15 and the 10 new EU member countries that joined the EU in 2004. The four major findings of this paper are: (1) panel unit root tests find evidence of price convergence for about 70% of all product groups, (2) the results are sensitive to the choice of the numeraire country implying that any conclusions must be based on all bilateral combinations, (3) the average half life across all product groups is 2.0 years, (4) the overall evidence for the law of one price is weaker in the 10 new EU member countries than in the EU-15.

Growth and inflation forecasts for Germany a panel-based assessment of accuracy and efficiency

We analyse forecasts of professional forecasters for Germany regarding the time span from 1970 to 2004. This novel panel data set renders it possible to assess the accuracy and efficiency of growth and inflation forecasts more efficiently than in previous studies. We argue that the forecasts are, on average, unbiased and weakly—but not strongly—efficient. Using model confidence sets suggested by Hansen et al. (2004), we find that, besides the effect of diverging forecasting dates, no other substantial differences in forecasting quality among forecasters exist. Nevertheless, on the basis of a direction-of-change analysis we argue that it is not always advisable to listen to the majority of forecasters.

Building blocks in the economics of mandates

The paper constructs an asymmetric information model to investigate the efficiency and equity cases for government mandated benefits. A mandate can improve workers’ insurance, and may also redistribute in favour of more ‘deserving’ workers. The risk is that it may also reduce output. The more diverse are free market contracts—separating the various worker types—the more likely it is that such output effects will on balance serve to reduce welfare. It is shown that adverse effects can be reduced by restricting mandates to larger firms. An alternative to a mandate is direct government provision. We demonstrate that direct government provision has the advantage over mandates of preserving separations.

Constitutional choice and European immigration policy

The EU’s immigration policy is evaluated from the standpoint of constitutional economics. The main conclusion is that European immigration policy is trapped in a system of constitutional regulations that is too rigid as it is exclusively oriented towards the protection and securitisation of European borders. As such, it is not capable of allowing the development of a problem-solving capacity based on successive trials, and this produces negative outcomes for the whole of the EU.

Extending the Learning-By-Exporting Hypothesis: Introducing a Credit Constraint

This paper develops a theoretical framework which can be used to examine policy implications from the learning-by-exporting hypothesis. This work builds on previous theoretical literature by introducing a credit constraint. When credit is available, the analysis suggests that supporting a learning sector via an export subsidy is not necessarily advised to improve social welfare. The learning sector’s goods may be over-produced (relative to another non-tradable sector goods) when consumers can borrow freely for their consumption. If the learning sector’s goods are over-produced, social welfare will be improved via a tax on production.
