Retailing Innovations in a Globalizing Retail Market Environment

In recent years, the combination of economic growth and population growth in emerging markets and less developed markets has accelerated the progression of globalization of retailing and globalization by retailers. The challenges faced by global and globalizing retailers (retailers who currently have or intend to establish a market presence in mature markets, emerging markets and less developed markets) can be more daunting compared to those faced by firms in other industries such as automobiles, steel, and computers. Retailing innovations that are responsive to the characteristics of distinctive national markets and broader aggregations of markets such as mature, emerging and less developed markets are critical to the success of global and globalizing retailers. Against this backdrop, this paper focuses on retailing innovations in the context of a globalizing retailing environment. It attempts to shed insights into the characteristics of retailing innovations conducive to superior performance in distinctive national markets and across broader aggregations of markets. Towards this end, we first examine the environmental conditions of markets in different development stages, namely mature, emerging and less developed markets, and explore consumer based, industry based, and legal/regulatory based challenges faced by globalizing retailers in these markets. Second, we show how these challenges can be transformed into opportunities with retailing innovations. We conclude with a roadmap for future research and present propositions on future development with respect to retailing innovations in these markets.     

A nonnormative theory of inflation and central bank independence

A Nonnormative Theory of Inflation and Central Bank Independence. — The authors study monetary policy under different central bank constitutions when the labor-market insiders set the minimal wage so that the outsiders are involuntarily unemployed. If the insiders are in the majority, the representative insider will be the median voter. The authors show that an independent central bank, if controlled by the median voter, does not produce a systematic inflation bias, albeit equilibrium employment is too low from a social welfare point of view. A dependent central bank, in contrast, is forced by the government to collect seigniorage and to take the government’s re-election prospects into account. The predictions of their theory are consistent with the evidence that central bank independence decreases average inflation and inflation variability, but does not affect employment variability.     

The euro: Major policy implications for Europe and the global economy

The paper examines the potential of the euro as an international currency. Owing to a large home base the long‐run potential is substantial. Much depends on whether the European Central Bank will be able to gain the reputation of a tough authority that issues a stable currency. Based on a comparison with the concepts of monetary targeting and inflation targeting, it is argued that the ECB's policy strategy is inferior as regards providing guidance to inflation expectations. The paper also discusses exchange rate policy and concludes that it is unlikely that Europe will join a new international exchange rate system.     

Political Macroeconomics: A Survey of Recent Developments

The paper surveys political macroeconomics, covering its development from Rogoff's conservative central banker to the most recent discussions of monetary policy and institutional design. Topics include the inflation-stabilization trade-off, central bank independence with escape clauses and overruling with costs, inflation targets, performance contracts for monetary authorities, and the consequences of output persistence for these issues. Further topics are the political business cycle when output is persistent, the political macroeconomics of fiscal policy, the government spending bias, and the game-theoretic interaction between fiscal and monetary policy. All work is discussed within a coherent analytical framework.

Is it up to the industrialised countries to finance the developing countries’ deficits?

Over the past decade the non-oil developing countries’ external debt has shown a more than threefold increase, a trend that may be expected to continue in the foreseeable future. In response to the recipient countries’ changing needs, private lending, their principal source of credit, will have to take different forms involving the creation of new multilateral facilities designed to place a bigger pool of long-term funds at the developing countries’ disposal.
