Defence Industry Transformation in Russia: Evidence from a Longitudinal Survey

The article is devoted to the new phenomena in the market transformation of the Russian defence-industrial complex. Based on the data generated by the repeated survey of the CEOs (general directors) of defence enterprises in 1995‐99, it examines economic performance of enterprises, their conflicts with the government and efforts at internal restructuring brought about by reductions of Russia's defence spending, mass privatisation and opening up of the domestic market. We found that despite the dramatic reduction in defence orders, inconsistent government policies and extremely unfavourable macroeconomic environment, the Russian defence industry has made significant progress in its adjustment to the market. Even before the devaluation of the ruble in the autumn of 1998 economic performance of defence enterprises had been gradually improving; it entered a virtual boom since then. Contrary to widely held views, the painful experience of the 1990s has not made the top managers of the defence industry more hostile to reforms: at the end of the decade they were generally more supportive of the market than in 1995.     

Consumer search markets with costly revisits

This paper characterizes equilibrium outcomes in consumer search markets taking the cost of going back to stores already searched explicitly into account. We show that the optimal sequential search rule under costly revisits is very different from the traditional reservation price rule in that it is non-stationary and not independent of previously sampled prices. We explore the implications of costly revisits on market equilibrium in two celebrated search models. In the Wolinsky model, some consumers search beyond the first firm. In this class of models, costly revisits do make a substantive difference and their impact can be of the same order of magnitude as the initial search cost. In the Stahl oligopoly search model where consumers do not search beyond the first firm, there remains a unique symmetric equilibrium that has firms use pricing strategies that are identical to the perfect recall case.     

Earnings and Equity Valuation in the Biotech Industry: Theory and Evidence

We examine how the price-earnings relation varies with the uncertainty about and the quality of a firm's investments. We develop a real option valuation framework to capture investment and abandonment options in the research-intensive biotechnology industry. We hypothesize that the price-earnings relation will be V-shaped and change over the firm 's life cycle. We also show how nonfinancial information affects the pricing of earnings. Our empirical findings are based on a sample of 301 biotechnology firms that made IPOs between 1980 and 2000, and are generally consistent with our predictions.     

A cospectral analysis of exchange rate comovements during Asian financial crisis

Comovements of exchange rates before and during Asian financial crisis are examined using cross-spectral methodology. The paper proposes and implements a simple frequency-domain-based test for contagion that avoids biases of the correlation breakdown tests used in the extant literature. The Asian crisis is found to be manifest in greater comovements along high-frequency components. Calculated changes in the high-frequency portion of the covariance indicate a contagion for 48 out of the possible 66 pairs of countries in the sample.     

Constant per capita consumption paths with exhaustible resources and decaying produced capital

We introduce decay in produced capital and exogenous technical progress to the recent “Solow Model” of Asheim et al. with population growth and observe the possible collapse of the economy given too high a rate of decay. “Enough” technical progress can restore sustainable per capita consumption.     

A model in which monetary policy is about money

Optimal monetary policy is studied in a model with (i) heterogeneity in the degree to which different people are monitored (have publicly known histories); (ii) idiosyncratic shocks that give rise to heterogeneity in earning and spending realizations; and (iii) central-bank intervention in a “market” in claims or credit in which the participants are those who are heavily monitored. A special case of the model has everyone perfectly monitored. In that case, there is no role for money and no role for central-bank intervention. In the example displayed with imperfect monitoring, optimal intervention is not simple.     

PERIODIC SEQUENCES OF ARBITRAGE: A TALE OF FOUR CURRENCIES

This paper investigates arbitrage chains involving four currencies and four foreign exchange trader‐arbitrageurs. In contrast with the three‐currency case, we find that arbitrage operations when four currencies are present may appear periodic in nature, and not involve smooth convergence to a ‘balanced’ ensemble of exchange rates in which the law of one price holds. The goal of this article is to understand some interesting features of sequences of arbitrage operations, features which might well be relevant in other contexts in finance and economics.     

Privatisation of the Russian Defence Industry: Ownership and Control Issues

This article analyses the outcome of privatisation in the Russian defence industry in the second part of the 1990s. It is based on the results of the longitudinal survey of defence enterprises conducted over the period 1995‐99 in the main defence production regions of Russia: Moscow, St Petersburg, Central European region, Western Siberia, Volga region, the Urals and the Far East. Using the survey data, we investigate the distribution of ownership in defence enterprises and examine the non-linear relationship between ownership and control inside these enterprises. We also test the hypothesis of the growing criminal influence in defence enterprises and outline a possible future scenario for privatisation in the defence industry.     

Snipers, Stalkers, and Nibblers: Online Auction Business Ethics

Spirited disagreement exists among online auction participants over the ethics of sniping: delaying one's bid until the closing seconds of an online auction. Through analysis of the structural features of online auctions and by deploying Rawls's (1955) distinction between justifying an action under a practice and justifying the practice itself, I argue that: (i) the disagreement is better conceived as one over the ethics of online auction hosting (and therefore, over business ethics) than over the ethics of online auction participation; (ii) so conceived, the argument against sniping is nonetheless implausible; and (iii) the disagreement remains interesting not on the merits, but for the curious fact that it is bidders who complain about sniping.     

Sufficient Decisions in Multi‐Sided and Multiproduct Markets

We show that in many models where firms make multiple decisions, analysis can be made more tractable by re‐formulating the model into one in which each firm makes a single choice, which we call a sufficient decision. The transformation allows application of standard techniques in these settings, including pass‐through for tax incidence and upward pricing pressure for merger analysis. The transformation works because the assumption of profit maximization links the firms’ decisions together. Examples include models of monopoly and oligopoly in two‐sided markets, where a natural sufficient decision may be the number of transactions that the firm facilitates, and multiproduct markets.
