Modelling the inflation process in transition economies: Empirical comparison of Poland, Hungary and Czech Republic

This paper starts from the observation that inflation in transition economies appears to be persistently high and volatile and attempts to provide some empirical characterisation of the inflation process in three such transition economies: Poland, Hungary and Czech Republic. We first consider the role of monetary growth as a major causal factor for inflation in these economies, and argue that the evidence provides rather weak support for the causal relationship. We then propose a transition economy cost-plus model and estimate this using the equilibrium-correction modelling (ECM) strategy augmented by introduction of a number of transitory factors and changes in the internal structure of the real economy which we believe may have had a significant impact on inflation in these economies. We show that this approach enables us to account for long-run inflation in these economies from the early 1980s to the present despite the turbulence of the latter part of the sample period. Our results support wage and exchange rate based inflation policies.     

Equilibrium Exchange Rates in Transition Economies: Taking Stock of the Issues*

Abstract. In this paper, we present an overview of a number of issues relating to the equilibrium exchange rates of transition economies of the former soviet bloc. In particular, we present a critical overview of the various methods available for calculating equilibrium exchange rates and discuss how useful they are likely to be for the transition economies. Amongst our findings is the result that the trend appreciation usually observed for the exchange rates of these economies is affected by factors other than the usual Balassa–Samuelson effect, such as the behaviour of the real exchange rate of the open sector and regulated prices. We then consider three main sources of uncertainty relating to the implementation of an equilibrium exchange rate model, namely: differences in the theoretical underpinnings, differences in the econometric estimation techniques, and differences relating to the time‐series and cross‐sectional dimensions of the data. The ensuing three‐dimensional space of real misalignments is probably a useful tool in determining the direction of a possible misalignment rather than its precise size.     

Unemployment in East and West Europe

We use new 1991–2005 panel data to address the issue of unemployment in Central-East Europe. We compare the evolution of unemployment, its dynamics and related phenomena in five former communist economies in the Central Europe and use the geographically close West Germany as a benchmark for a mature market economy. We identify the differences and similarities in the evolution of the key labor market variables and contrast different outcomes with the diverse initial conditions and subsequent paths. All countries have experienced aggregate demand shocks, structural shocks and hysteresis. Despite diverse initial conditions and subsequent paths, the patterns observed are surprisingly similar. The eastern part of Germany appears to be a special case with extraordinary high unemployment inflows. Contrary to the theoretical models, in the transition economies we do not observe an initially rapid rise in the inflow rate, followed by a convergence of this rate to the levels of market economies. Rather, there is a relatively gradual rise in the inflow rate towards the level of market economies. The differences in unemployment rates turn out to be attributable to a considerable extent to the actual differences in the inflow rates. The trajectories in the unemployment-vacancy space observed in the Central-East European countries increasingly resemble those observed in the developed market economies. Interestingly, these similarities arise despite differences in the institutional setting across these economies.     

Entrepreneurial migrants from/in emerging economies: breaking taboos and stereotypes

Entrepreneurial migration from/in emerging economies, as grand societal and humanitarian challenges that we currently face, underscores the need for scholarly research. In our role as social science researchers, this special issue aimed to stimulate scholars from different social science fields to rethink more broadly about the opportunities for making an impact with our research focus on entrepreneurial migration from/in emerging economies. This article provides an overview of the theoretical, empirical, managerial, and policy implications of entrepreneurial migrants from/in emerging economies research. It puts forward key concepts and measures, explores the relations within the current broader literature on migration and entrepreneurship, and identifies several gaps that represent future research questions. We also introduce eight papers in a special section of this issue, which offer answers to critical gaps and questioning some taboos/stereotypes related entrepreneurial migrants. We conclude by outlining an agenda for engaging the academic community to extend research on entrepreneurial migrants from/in emerging economies. It is the perfect time to “make a difference” through our research, teaching, and interaction with multiple socioeconomic agents to constitute impacts that “endorse a real transformation” for supporting the migrants’ community.

     

Constrained inefficiency in GEI: A geometric argument

In this paper we use global analysis to study the welfare properties of general equilibrium economies with incomplete markets (GEI). Our main result is to show that constrained Pareto optimal equilibria are contained in a submanifold of the equilibrium set. This result is explicitly derived for economies with real assets and fixed aggregate resources, of which real numéraire assets are a special case. As a by product of our analysis, we propose an original global parametrization of the equilibrium set that generalizes to incomplete markets the classical one, first, proposed by Lange [Lange, O., 1942. The foundations of welfare economics. Econometrica 10, 215–228].     

Exploring the Impact of Agricultural Price and Trade Policy Reform under Transition in Albania

Agricultural policy decision making in economies undergoing transition to market is in need of empirical tools for assessing the impact of alternative policy options. The econometric means available for such exercise, however, are limited for lack of data and structural breaks in economic behaviour. Synthetic, partial equilibrium, multi-market models offer a potential alternative. Such models have been used extensively, even in advanced economies, to offer valuable insights on the impact of alternative policy options. This paper shows the use of such a partial equilibrium, multi-market, synthetic-type model as a tool for agricultural policy analysis in a country in transition. The model is applied for Albania, a predominantly agricultural country that, after a period of centralism and autarky, aims to re-join the international economic system. The model, albeit its many limitations, offers some useful insights on the impact of alternative options available for agricultural price and trade policy. This revised version was published online in July 2006 with corrections to the Cover Date.

International trade and hedging in economies in transition

This paper develops a general equilibrium framework to analyze risk management policies in economies in transition. By cross-hedging against real exchange rate risk exposures, these economies can increase their gains from international trade. We suggest that countries with emerging forward markets can gradually introduce the risk sharing markets, as limiting resources may prevent them from introducing complete hedging markets in the first place. Thus the growing demand for risk management instruments can be gradually met and it would be welfare enhancing. Economies in transition benefit when hedging devices are offered by financial markets, irrespective of whether the hedging instruments are de facto perfect or not.     

Working in the digitized economy: HRM theory & practice

In our introduction to this special issue on the gig economy, we provide some context to how and why this phenomenon should be studied, with a particular emphasis on Human Resource Management. We then describe the four articles that comprise the special issue, and we note some common themes. Our introduction concludes with some suggestions for future research on the gig economy.     

A Logit Model with Missing Information Illustrated by Testing for Hidden Unemployment in Transition Economies

In an important paper, Dempster, Laird and Rubin (1977) showed how the expectation maximization (EM) algorithm could be used to obtain maximum likelihood estimates of parameters in a multinomial probability model with missing information. This article extends Dempster, Laird and Rubin's work on the EM algorithm to the estimation of a multinomial logit model with missing information on category membership. We call this new model the latent multinomial logit (LMNL) model. A constrained version of the LMNL model is used to examine the issue of hidden unemployment in transition economies following the approach of Earle and Sakova (2000) . We found an additional 0.5% hidden unemployment among workers describing themselves as self‐employed in the transition economies of Central and Eastern Europe.     

Recursive equilibrium in stochastic OLG economies: Incomplete markets

We prove generic existence of recursive equilibrium for overlapping generations economies with uncertainty and incomplete financial markets. Generic here means in a residual set of utilities and endowments. The result holds provided there is sufficient intragenerational household heterogeneity, and transition probabilities and the asset payoff matrix satisfy mild regularity conditions. The paper also provides a new methodological technique to establish comparative statics, or perturbation, properties in such environments.     

Pitfalls in estimating equilibrium exchange rates for transition economies

The literature on equilibrium exchange rates for the central and eastern European countries has mushroomed in recent years. In this paper, we discuss the econometric pitfalls involved in such estimations and endow the reader with the methodological ingredients to avoid such biases. We review the commonly used approaches and identify problems related to the most straightforward econometric procedures as they often do not take the transition process properly into account. As an alternative, we propose a two-stage “out-of-sample” strategy that consists of estimating the relationship between the exchange rates and fundamentals and the extrapolation of these relationships to transition economies.     

Implementation of marginal cost pricing equilibrium allocations with transfers in economies with increasing returns to scale

This paper considers implementation of marginal cost pricing equilibrium allocations with transfers for production economies with increasing returns to scale. We present a mechanism whose Nash equilibrium allocations coincide with the set of marginal cost pricing equilibrium allocations with transfers that characterizes Pareto efficient allocations for economies with non-convex production technologies. We allow production sets and preferences to be unknown to the planner. The mechanism has some nice properties such as feasibility, continuity, and finite-dimension of message space. Furthermore, it works not only for three or more agents, but also for two-agent economies.     

Firm-level determinants of tax evasion in transition economies

Business tax evasion is an important issue for governments. Yet the factors that determine business tax evasion have not been sufficiently examined in the literature in general, and in transition contexts in particular. To address this gap, this study uses the WB/EBRD Business Environment and Enterprise Performance Survey (BEEPS) database with a sample of over 12,692 firms from 26 transition economies. Applying various modelling strategies, we argue that tax evasion is a function of firm-level and institutional-level variables. We contribute to the literature by providing robust evidence showing that the perceived tax burden has a positive impact on tax evasion. We also find that the tax evasive behaviour of firms is positively influenced by low trust in government and in the judicial system as well as by higher perceptions of corruption and higher compliance costs. We find that smaller firms, individual businesses and firms in sectors that are less visible to the tax administration are more likely to get involved in evasive behaviour. Overall, institutional factors play an important role in determining firms’ tax evasion behaviour in transition economies. This finding has important policy implications.     

The role of interest rates during the transition to a market economy

We construct a simple two period model of an economy in transition from being centrally planned to being market oriented. Using this model, we draw certain positive conclusions about economic policies that reduce distortions during the transition period. In particular, we focus on the role of interest rates, a market parameter that has previously been almost entirely ignored in planned economies. Using stylized data derived from Czechoslovakia, we show that increase in nominal interest rates can actually be welfare-improving by partially compensating for the distortions induced by the transition process.The model is sufficiently general to be applied to a number of transition economies, and we use the cases of Czechoslovakia, the USSR, and China as examples of some of the phenomena that we are trying to explain. We show that the model generates a constrained, suboptimal equilibrium. In particular, we see that raising interest rates during the transition period reduces repressed savings, brought about by shortages in the controlled market. An improvement in consumer utility can therefore be brought about.A large part of the work in this paper was carried out while I was a Visiting Scholar in the Research Department of the International Monetary Fund. I would like to thank Mario Blejer, Nadeem Ul-Haque, and Sweder Van Wijnbergen for helpful comments.

Urban Agglomeration and Dispersion: A Synthesis of Alonso and Krugman

Urban agglomeration becomes increasingly important because of the globalization of world economies. This paper is a general equilibrium analysis of urban agglomeration economies due to product variety, and agglomeration diseconomies due to intra-city congestion in a two-city system framework. Special attention is paid to the impacts of transportation cost decrease on urban concentration and dispersion. Our main result is that dispersion necessarily takes place when the transportation cost is sufficiently low. We also conduct numerical calculations using specific parameter values, and depict a structural transition from dispersion to agglomeration, and then re-dispersion when the transportation costs decrease monotonically over time. Finally, we observe that dispersion is usually bad as compared to agglomeration, from a welfare point of view.     

Trends and cycles in small open economies: making the case for a general equilibrium approach

Economic research into the causes of business cycles in small open economies is almost always undertaken using a partial equilibrium model. This approach is characterized by two key assumptions. The first is that the world interest rate is unaffected by economic developments in the small open economy, an exogeneity assumption. The second assumption is that this exogenous interest rate combined with domestic productivity is sufficient to describe equilibrium choices. We demonstrate the failure of the second assumption by contrasting general and partial equilibrium approaches to the study of a cross-section of small open economies. In doing so, we provide a method for modeling small open economies in general equilibrium that is no more technically demanding than the small open economy approach while preserving much of the value of the general equilibrium approach.     

Property rights,rent-seeking and aggregate outcomes in transition economies

We analyze the macroeconomic consequences of rent-seeking activities in transition economies. Due to strategic complementarities in modernization of firms, multiple equilibria can occur. However, given the institutional vacuum, the macroeconomic outcomes crucially depend on how property rights are distributed and on the number of contestants over the surplus of the firms. Under inside ownership, the distributional conflict between inside workers, within each firm, may lead to a bad equilibrium without modernization. Outside ownership adds another level of distributional conflict (between insiders and outsiders) but may lead to a high equilibrium with modernization as the number of outside owners increases.
