Integration of FSU/economies in transition into the World Trade Organization1

Membership of the World Trade Organization is a goal for many transition economies. This paper discusses what is involved in WTO membership, the information required and the commitments imposed upon members. After reviewing the accession process in general, the topic is illustrated by the recent example of Bulgaira and Mongolia.     

Monetary policy in open economies

The recent literature on monetary policy in open economies has produced a strong presumption in favor of activistic policy and flexible exchange rates. We argue that this result may owe much to the combination of two commonly made assumptions: That nominal goods prices are rigid. And that the monetary authorities have a lot of information about the economy. When the source of nominal rigidity is found in wages and monetary policy is conducted according to less information demanding rules (such as a standard interest rate rule) policies that stabilize the money supply or the nominal exchange rate may perform better.     

On the emergence of public education in land-rich economies

We analyze the emergence of large-scale education systems by modeling the incentives that the economic elite could have (collectively) to accept taxation destined to finance the education of credit-constrained workers. Contrary to previous work, in our model this incentive does not arise from a complementarity between physical and human capital in manufacturing. Instead, we emphasize the demand for human-capital-intensive services by high-income groups. Our model seems capable to account for salient features of the development of Latin America in the 19th century, where, in particular, land-rich countries such as Argentina established an extensive public education system and developed a sophisticated service sector before starting significant manufacturing activities.     

Monetary policy games and international migration of labor in interdependent economies

"In this paper we incorporate the possibility of international migration into a monetary policy game played by governments in unionized interdependent economies. We show that contrary to usual presumptions, established by earlier studies that ignore the possibility of international migration, inter-government cooperation in the monetary field may well turn out to be advantageous. This has important implications for the European economies, since it suggests that measures taken towards encouraging international migration within EU [the European Union] will not only harmonize the European labor markets but will also make monetary policy cooperation within Europe, as required by the Maastrict Treaty, more advantageous."     

Monetary policy co-movement and spillover of shocks among BRICS economies

The 2008 global financial crisis has revealed the possibility of cross-border spillover effects of domestic Monetary Policy (MP) on financial stability and capital flows around the world. Recognizing these facts, Central Banks in Advanced Economies (AE) have undertaken simultaneous Monetary Policy actions to minimize collateral damage and contain financial risks. In this paper, we investigate whether a similar spillover and co-movement of Monetary Policy exist among BRICS countries. Specifically, we study the transmission of monetary policy shocks among the member countries using monthly data. We use the method of Principal Component Analysis (PCA) and Vector Autoregression Model to identify possible dynamic relationships. Our results indicate possible co-movement in interest rates and significant cross-border transmission of monetary policy shocks among the BRICS countries.     

Monetary policy and commodity terms of trade shocks in emerging market economies

Commodity terms of trade shocks have continued to drive macroeconomic fluctuations in most emerging market economies. The volatility and persistence of these shocks have posed great challenges for monetary policy. This study employs a New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model to evaluate the optimal monetary policy responses to commodity terms of trade shocks in commodity dependent emerging market economies. The model is calibrated to the South African economy. The study shows that CPI inflation targeting performs relatively better than exchange rate targeting and non-traded inflation targeting both in terms of reducing macroeconomic volatility and reducing the losses of a non-benevolent central bank. However, macroeconomic stabilisation comes at a cost of increased exchange rate volatility. The results suggest that the appropriate response to commodity induced exogenous shocks is to target CPI inflation.     

Monetary and fiscal policy interactions: Evidence from emerging European economies

This paper examines the interactions between fiscal and monetary policy for some former transition, emerging European economies over the 1995Q1–2010Q4 period by using a Markov regime-switching model. We consider the monetary policy rule proposed by Taylor (1993) and the fiscal policy rule suggested by Davig and Leeper (2007) in accounting for monetary and fiscal policy interactions. Empirical results suggest that monetary and fiscal policy rules exhibit switching properties between active and passive regimes and all countries followed both active and passive monetary policies. As for fiscal policy, the Czech Republic, Estonia, Hungary, and Slovenia seem to have alternated between active and passive fiscal regimes while fiscal policies of Poland and the Slovak Republic can be characterized by a single fiscal regime. Although the policy mix and the interactions between monetary and fiscal policy point a diverse picture in our sample countries, the monetary policy seems to be passive in all countries after 2000. This finding is consistent with the constraints imposed by European Union enlargement on monetary policy.     

Monetary transmission in three central European economies: evidence from time-varying coefficient vector autoregressions

We study the transmission of monetary policy to macroeconomic variables with structural time-varying coefficient vector autoregressions in the Czech Republic, Hungary and Poland, in comparison with that in the euro area. These three countries have experienced changes in monetary policy regimes and went through substantial structural changes, which call for the use of a time-varying parameter analysis. Our results indicate that the impact on output of a monetary shock changed over time. At the point of the last observation of our sample, the fourth quarter of 2011, among the three countries, monetary policy was most powerful in Poland and not much less strong than the transmission in the euro area. We discuss various factors that can contribute to differences in monetary transmission, such as financial structure, labour market rigidities, industry composition, exchange rate regime, credibility of monetary policy and trade openness.     

Monetary policy implementation and transmission in the European Monetary Union

I discuss possible problems engendered by loss of national monetary policies, and study them from three empirical perspectives. First, are business cycles sufficiently synchronized across EMU member countries? The evidence suggests that economic activity in those countries has become increasingly correlated in the 1990s, and that policy co–ordination has played a role in generating that outcome. Second, are there asymmetries in the mechanisms through which policy affects economic activity? The paper documents that policy transmission was indeed heterogeneous in the member countries, and that structural and financial factors were sensibly related to cross–country differences in the response of output to a monetary policy shock. Third, how is policy implemented in an environment of diverse business cycle fundamentals and transmission mechanisms? Estimation of monetary policy reaction functions finds that the European Central Bank is closer to an aggregate of the central banks in Germany, France, and Italy than to the Bundesbank alone.     

A note on the stability of endogenous cycles in Diamond's model of search and barter

In this note stability conditions for the endogenous rational expectations business cycles detected by Diamond and Fudenberg (1989) are derived. It is shown that for the trading externality underlying their example, bifurcating cycles are always stable, i.e., there always exists a continuum of rational expectations equilibrium paths converging to the cycle.I am grateful to Reiner Franke and the referees of this Journal for their helpful comments and suggestions. I also thank my colleagues Wolfgang Hofmann and Bill Brunton for checking the language of the paper.     

日元与人民币:区域内货币合作抑或货币竞争

针对日元与人民币的关系问题,笔者研究发现:(1)日元与人民币现阶段都无法成为区域内锚货币,两者尚未具备区域内货币竞争的条件;(2)中日两国产业结构差异和贸易互补性使得两国货币竞争没有必要;(3)货币危机和中日双边贸易发展内在地推动两国加强区域内货币合作;(4)日本对华贸易与人民币汇率之间没有长期稳定的协整关系.据此,仅从经济和金融角度考虑,推进日元与人民币区域内货币合作而非货币竞争对中日双方都是有利的.     

A note on multiproduct economies of scale and economies of scope

Two measures of (local) economies of scale for a firm producing more than two products are derived using measures of product-specific economies of scale and economics of scope. The latter is especially useful for econometric estimation and testing.     

Competition policy in the transitional economies

Conclusion It is very encouraging to note how much progress has been made with competition policy, especially in the four Visegrad countries. One might add that the developments were not merely in the legal front; in both Poland and Hungary the competition offices have forceful and impressive heads who have used their considerable discretion to shape anti-monopoly practice in their respective countries. The weakness of Bulgaria and Romania on this front is a reflection of the more general problems in implementing market-based reforms, and in establishing true independence between the economic and the political sphere.Nonetheless, our discussion indicates several cases where further developments could be made. The legislative structures in the reforming economies perhaps place excessive faith on quantitive indicators of dominance, and in many countries the independence of the competition offices from the political system is insufficient. The reliance on EU-type legislative structures perhaps also leads to insufficientper se prohibitions.

De-industrialisation and the balance of payments in advanced economies

This paper defines de-industrialisation as a secular declinein the share of manufacturing in national employment. De-industrialisation,in this sense, has been a widespread feature of economic growthin advanced economies in recent decades. The paper considersbriefly what explains this development and quantifies some ofthe factors responsible. It then examines the experience ofBritain and America, which are two countries that have combinedrapid de-industrialisation with a strong overall economic performance.The paper considers both the domestic situation of manufacturingindustry in these countries and its foreign trade performance.It concludes by examining in detail the British balance of payments,and documenting how improvements in the non-manufacturing spherehave helped offset a worsening performance in manufacturingtrade.     

Scope economies in the pharmaceutical sector

The paper’s objectives are twofold: to propose an experimental simulation to measure scope economies between pairs of submarkets and to point out the role of submarkets in explaining the concentration level in the pharmaceutical market. We simulate scope economies consistent with the diversification choices of large international companies in the years 1987 and 1997. Our results suggest that: i) the random diversification (that is no scope economies hypothesis) is rejected, and ii) scope economies are significant. (JEL: C15, D21, L11, L65)
