MARKETS FOR INFLATION‐INDEXED BONDS AS MECHANISMS FOR EFFICIENT MONETARY POLICY

We consider a continuous‐time framework featuring a central bank, private agents, and a financial market. The central bank's objective is to maximize a functional, which measures the classical trade‐off between output and inflation over time plus income from the sales of inflation‐indexed bonds minus payments for the liabilities that the inflation‐indexed bonds produce at maturity. Private agents are assumed to have adaptive expectations. The financial market is modeled in continuous‐time Black–Scholes–Merton style and financial agents are averse against inflation risk, attaching an inflation risk premium to nominal bonds. Following this route, we explain demand for inflation‐indexed securities on the financial market from a no‐arbitrage assumption and derive pricing formulas for inflation‐linked bonds and calls, which lead to a supply‐demand equilibrium. Furthermore, we study the consequences that the sales of inflation‐indexed securities have on the observed inflation rate and price level. Similar to the study of Walsh, we find that the inflationary bias is significantly reduced, and hence that markets for inflation‐indexed bonds provide a mechanism to reduce inflationary bias and increase central bank's credibility.

Privatization of businesses and flexible investment: a real option approach

In this article, we study the situation, where the opportunity is given to invest into a government-owned business by partial privatization to a private company. After payment of an initial installment cost, the private company’s investments are flexible within a range [0, k] until the business is completed. We model the problem in a real option framework, using geometric mean reversion to describe the dynamics of the business. We determine the optimal time for the private company to enter and pay the initial installment cost as well as the optimal dynamic investment strategy that it follows afterward. For the latter, analytic solution cannot be obtained. We use quadratic splines in order to solve the corresponding dynamic programming problem. Finally, we determine the optimal degree of privatization in our model from the government’s perspective.     

Dynamic voluntary provision of public goods with uncertainty: a stochastic differential game model

Fershtman and Nitzan (Eur. Econ. Rev. 35:1057–1067, 1991) presented a continuous dynamic public good game and solved the model for feedback Nash equilibria. Wirl (Eur. J. Polit. Econ. 12:555–560, 1996) extended the model and considered nonlinear strategies. Both models do not include uncertainty and hence neglect an important factor in the theory of public goods. We extend the framework of Nitzan and Fershtman and include a diffusion term. We consider two cases. In the first case, the volatility of the diffusion term is dependent on the current level of the public good. This set-up will in principle lead to the same type of feedback strategies computed under certainty. In the second case, the volatility is dependent on the current rate of public good provision by the agents. The results are qualitatively different. We provide a detailed discussion as well as numerical examples. In particular, we show that in both cases uncertainty signifies the free rider effect.     

PRIVATIZATION IN AUSTRIA: causes and consequences

ABSTRACT*: This paper examines the privatization experiences in Austria. Nationalized industries historically played a great role in Austria. Mainly for budgetary reasons a far reaching privatization was rapidly effected, the state holding company acting as the privatization agency. In privatization decisions not only micro-economic but also macro-economic and structural aspects had been considered, such as the impact on national research and development, employment perspectives and market structures, all this being of special relevance for privatization projects in small countries. From the point of view of both the privatized enterprises and the economy as a whole, privatization in Austria has been successful. Privatizations also had a strong impact on Austrian capital markets: 90 per cent of privatizations were carried out on the stock exchange. In 1995 30 per cent of the turnover of the Vienna stock exchange was accounted for by shares of private enterprises.     

Living on the slopes: entrepreneurial preparedness in a context under continuous threat

ABSTRACT

In this paper, we examine how entrepreneurs living in communities under continuous threat prepare themselves to continue with their enterprising activities or engage in new ones after the expected crisis occurs. Most of the crisis literature on disasters and entrepreneurship focuses on aftermath responses, but the antecedents of such entrepreneurial behaviour and its connection to past and future crises remains largely unexplored. Based on a two-stage exploratory study pre and post the Calbuco Volcano eruptions in 2015 and 2016 in Chile, we introduce the notion of entrepreneurial preparedness in a context of continuous threat and elaborate on its four central attributes: anchored reflectiveness, situated experience, breaking through, and reaching out. Subsequently, our work develops a refined understanding of pre and post-disaster entrepreneurship and offers a novel base for theorizing on the relationship between entrepreneurial preparedness in contexts of continuous threat.     

Marktstruktur und Preisverhalten in der österreichischen Industrie

Summary Being part of a larger investigation concerning forms and intensity of competition in the Austrian economy this paper deals with the characteristics of market structure and pricing behaviour in the industrial sector. Mainly based on a detailed questionnaire this study is representative for the group of larger Austrian industrial enterprises (sales of more than 100 Mill. AS) which produced more than two thirds of total industrial ouput. According to this study the dominant market structure of the Austrian industry is that of a close oligopoly. The subjective estimation of the price elasticity of demand by the firms participating in our survey was generally very pessimistic, being the lower the larger the market share of the respective firm.The most common principle of price formation for new products in the Austrian industry is a system of flexible full cost pricing, meaning cost orientation plus variable profit margins. Our study also shows that a large majority (60% resp. 80%) of the enterprises under investgation use discount, i.e. price differentiation in their pricing policies. These aspects indicate that-in line with marginalistic theories — demand situations obviously exercise a substantial influence on pricing behaviour. Considering the causes for price changes, however, cost oriented influences were clearly dominating. This stresses the great importance of the Austrian pricecontrol mechanism, the Paritätische Kommission, the institutionalized form of incomes policy in Austria.An econometric analysis of the process of price formation in the Austrian industry showed that the main factors of price changes were changes in labour costs and in international price levels, especially in the level of export prices. Our investigation also dealt with the question, whether differences in market-structure result in different, responses to demand fluctuations. Considering both the concepts of actual and potential competition it can be shown that enerprises in a more competitive situation react towards changes in demand conditions in a more stabilizing way that monopolistic firms: The reduce prices earlier in recession and they react to boom periods by expanding their capacities rather than by raising prices. Market structure and the intensity of competition thus seem to influence the position of the Phillips-curve in an economy.
