Trade and Diversity: Is There a Case for ‘Cultural Protectionism?’

Abstract. In contrast to the predictions of standard models of international trade, globalization critics are claiming that trade destroys diversity. We demonstrate that with endogenous sunk costs, trade integration in horizontally differentiated industries can indeed lead to a fall in diversity. Consumers are faced with a tradeoff between gains in real income and a loss in diversity, so that the impact on welfare is ambiguous. However, it is possible through fiscal policies to replicate pre-trade choices and still realize gains in real income. Thus, calls for a 'cultural protectionism' are not justified.     

Redistribution,state trading enterprises and ‘politically optimal’ tariffs

State trading enterprises (STEs) are widely used and can be viewed as instruments of trade policy. We analyse two aspects: the first is their potential trade distorting effect; the second is how they modify the case for the ‘politically optimal’ tariff. We show that the STE can reduce the need for a tariff designed for domestic redistribution. This result introduces some ambiguity about how STEs are interpreted: from a multilateralist perspective, they should be dealt with in the same way as other non‐tariff barriers; from a nationalistic perspective, they can reduce the need for ‘politically optimal.’     

Foreign market conditions and export performance: does ‘crowdedness’ reduce exports?

Abstract This paper analyzes the link between firm exports and the competitive environment in foreign markets. We derive a theory‐based econometric specification linking market‐specific exports to foreign demand and the degree of a market’s ‘crowdedness,’ which depends on the number and efficiency of firms competing there and the barriers impeding their access. Estimates on a large sample of Italian firms indicate that increased crowdedness has reduced Italian exports, but only by 0.2%–0.3% per year. This is substantially less than the contribution of other factors such as higher unit labour costs or weak demand growth in the EU15.     

Labour migration in the enlarged EU: a new economic geography approach

This paper studies the impact of migration policy liberalisation on international labour migration in the enlarged European Union (EU) in a structural economic geography approach. The liberalisation of migration policy would induce an additional 1.80–2.98% of the total EU workforce to change their country of location, with most of migrant workers relocating from the East to the West. The average net migration rate is decreasing in the level of integration, suggesting that from an economic point of view no regulatory policy responses are necessary to labour migration in the enlarged EU.     

A RE‐EXAMINATION OF REAL INTEREST PARITY IN CEECs USING ‘OLD’ AND ‘NEW’ SECOND‐GENERATION PANEL UNIT ROOT TESTS

This study applies ‘old’ and ‘new’ second‐generation panel unit root tests to check the validity of the long‐run real interest rate parity (RIP) hypothesis for ten Central and Eastern European Countries (CEECs) with respect to the Euro area and an average of the CEECs’ real interest rates. When the ‘new’ panel unit root tests are carried out relative to the Euro area rate as reference, we confirm the results of previous studies that support the RIP hypothesis, and the results of the ‘old’ tests used as a benchmark. Nevertheless, when the ‘new’ tests are performed using the average of the CEECs’ rate as reference, our results are mitigated, revealing that the hypothesis of CEECs’ interest rates convergence cannot be taken for granted. From a robustness analysis perspective, our findings indicate that the RIP hypothesis for CEECs should be considered with caution, because the RIP hypothesis is sensitive to the retained reference rate for computing the real interest rate differential, and also to the retained countries in the sample.     

Monetary integration in the ex‐Soviet Union: A ‘union of four’?*

The governments of four ex‐Soviet countries recently discussed forming a currency union. To examine the economic feasibility of this proposition, we use conventional techniques and show that the arrangement is likely to find it difficult to handle the lack of structural symmetry, the asymmetric pattern of shocks, and the lack of market flexibility among the potential participants. Moreover, the union would be a unilateral one. It would require an unusual degree of political commitment to survive. Nonetheless, there are some subtleties in the timing and pattern of mutual dependence between Russia and Kazakhstan, and to a lesser extent in Belarus, which may reduce the strain from a currency union in those countries. Otherwise, the black market will have to provide the necessary market flexibility.     

The ‘Troubling Tradeoffs’ Paradox and a Resolution

Ravallion ( 2012a ) argues that the Human Development Index (HDI) embeds questionable tradeoffs between the dimensions used to compute the index. To alleviate these problems he proposes the adoption of one of the indices developed by Chakravarty ( 2003 ). In this paper I identify the following paradox: while the Chakravarty indices clearly exhibit more sensible tradeoffs than the HDI, the HDI produces more sensible rankings than the Chakravarty indices. To solve the paradox I identify the axioms behind each methodology responsible for the unintuitive tradeoffs and rankings and illustrate how to develop an index with these questionable axioms removed. This approach can result in methodologies that exhibit more intuitive tradeoffs by design, as it seeks inputs from the public as to what those tradeoffs ought to be, and produces rankings that are more in line with what the HDI wishes to measure: human development and capabilities, as conceptualized by Sen ( 1985 ).     

Comments on ‘Forecasting with a real-time data set for macroeconomists’

The effects of data revision as removing measurement error on forecast model building is examined. I show various effects on model building using revised or instead real-time data. These effects include lag length selection and measured persistence. I then argue that in practice that one should include the entire dataset available (real-time and past revised data) in forecast construction.     

The brain drain, ‘educated unemployment’, human capital formation,and economic betterment1

Extending both the ‘harmful brain drain’ literature and the ‘beneficial brain gain’ literature, this paper analyzes both the negative and the positive impact of migration by skilled individuals in a unified framework. The paper extends the received literature on the ‘harmful brain drain’ by showing that in the short run, international migration can result in ‘educated unemployment’ and overeducation in developing countries, as well as a brain drain from these countries. A simulation suggests that the costs of ‘educated unemployment’ and overeducation can amount to significant losses for the individuals concerned, who may constitute a substantial proportion of the educated individuals. Adopting a dynamic framework, it is then shown that due to the positive externality effect of the prevailing, economy‐wide endowment of human capital on the formation of human capital, a relaxation in migration policy in both the current period and the preceding period can facilitate ‘take‐off’ of a developing country in the current period. Thus, it is suggested that while the migration of some educated individuals may reduce the social welfare of those who stay behind in the short run, it improves it in the long run.     

‘Beautiful Serbia’ ‐ objective and subjective outcomes of active labour market policy in a transition economy

This paper studies the causal impact of participation in the Beautiful Serbia programme providing training and temporary work in the construction sector in Serbia on labour market outcomes as well as on measures of subjective well‐being approximating individual welfare. According to our estimates, the positive impact of this particular programme appears much stronger when judged by subjective well‐being than when judged by the immediate labour market effect.     

Regionalization, public spending and growth: a stylized model dealing with ‘predatory states’

In this paper, a micro-founded model analyzing the effects of ‘regionalization’ on economic activity is developed. It shows that the spatial division of public competencies can have an impact on the growth rate via the efficiency of governmental choices: initially advantageous for weak levels, decentralization (/reduction of regional size) becomes limited due to the risk of underestimation of the real profitability of public expenditure by local governments (non-internalized cross-border effects). In accordance with the theory, a transversal estimation for a sample of 51 countries for the 1990s establishes a ‘bell-shaped’ relation between indicators of regionalization and the quality of governance.     

Interpreting foresight process impacts: Steps towards the development of a framework conceptualising the dynamics of ‘foresight systems’

Foresight programmes are usually evaluated in terms of the achievement of initial objectives and the scale and nature of direct, anticipated impacts, notwithstanding the difficulty of measuring such impacts. However, indirect and/or unanticipated impacts that fall outside the scope of specific programme goals and objectives have also been reported. These are mainly impacts associated with the foresight process itself, i.e. with the way in which foresight exercises are designed and implemented. These impacts typically fall in areas such as:

• Knowledge creation, diffusion and absorption;

• Social capital and networking;

• The evolution of strategies to cope with or escape from the negative consequences of a ‘risk society’.

The diversity of the above areas suggests that foresight process impacts should be interpreted through the lenses of epistemology, sociology, political science, management science and organisational theory. In parallel, given that developments in the above spheres are strongly associated with the evolution of ‘participatory knowledge societies’, this paper presents an interpretation of foresight process impacts within a conceptual framework that attempts to characterise such societies.

Additionally, such an interpretation is conceived as a step towards the development of a conceptual framework aimed at understanding the dynamics of ‘foresight systems’. This framework should be capable of explaining the interdependencies and inter-relationships between system elements such as actors, processes, inputs, outputs and impacts, as well as the interaction of the system with the broader socio-technological-economic-political environment.

The overall aim of the paper is to develop an impact assessment framework for foresight exercises that assesses the degree to which they promote the development of ’participatory knowledge societies’.

The paper is based primarily on research carried out during the preparation of a PhD thesis entitled “Assessing the contribution of Foresight to a more participatory knowledge society”. The research mainly involved a literature review of available documentation on past and present foresight programmes and their results.     

Comment on ‘Competition Tests with a Non‐Structural Model: The Panzar–Rosse Method Applied to Germany's Savings Banks’

Abstract. In a recent issue of this journal Gischer and Stiele (2009) applied the ‘Test for “Monopoly” Equilibrium’ advanced by Panzar and Rosse (1987) to German savings banks and came up with the claim that savings banks maximize profits under conditions of monopolistic competition in the meaning of Edward Chamberlin. Their proposition is not conclusive since it would require free entry and for savings banks to operate under increasing returns to scale. Available evidence, however, shows them being subject to constant or decreasing returns to scale. The empirical findings of Gischer and Stiele can more convincingly be explained by assuming savings banks abide by their legal goals to pursue the public interest.     

The CO2 ‘trade balance’ between Scotland and the rest of the UK: Performing a multi-region environmental input–output analysis with limited data

In this paper we attempt an empirical application of the multi-region input–output (MRIO) method proposed by Turner, Lenzen, Wiedmann and Barrett [Turner, K., Lenzen, M., Wiedmann, T., Barrett, J., 2007. Examining the global environmental impact of regional consumption activities — part 1: a technical note on combining input–output and ecological footprint analysis. Ecological Economics 62 (1), 37–44] in a recent issue of this journal in order to enumerate the CO2 pollution content of interregional trade flows between Scotland and the rest of the UK (RUK). We extend the analysis to account for direct emissions generation by households, as final consumers, and to a social accounting matrix (SAM), where a more comprehensive account of incomes and expenditures is possible. While the existence of significant data problems mean that the quantitative results of this study should be regarded as provisional, the interregional economy-environment IO and SAM framework for Scotland and RUK allows an illustrative analysis of some very important issues in terms of the nature and significance of interregional environmental spillovers within the UK and the existence of a CO₂ ‘trade balance’ between Scotland and RUK.     

Small is beautiful but large is not to be belittled: a comment on Eijffinger et al. [Eur. J. Political Economy 18 (2002) 365–374]

Eijffinger et al. [Eur. J. Pol. Econ. 18 (2002) 365] find that the research performance of the National Central Banks (NCBs) of the European System of Central Banks is inversely related to their size, or that “small is beautiful”. Their analysis is based on journal articles published by NCB researchers. In the case of the Bank of Italy, their data does not reflect the true number of papers published. Their conclusions may accordingly require modification.
