Future events are uncertain by their very nature. Therefore, people's risk preferences are likely to play a role in the valuation of allegedly guaranteed future outcomes. We show that future uncertainty conjointly with people's proneness to nonlinear probability weighting generates a unifying framework for explaining many anomalies in intertemporal choice, such as hyperbolic discounting and subadditivity of discount factors. Moreover, our approach implies that higher uncertainty of future prospects increases the hyperbolicity of discount rates, suggesting that institutional deficiencies such as lack of contract enforcement, may be a source ofnhyperbolic discounting behavior. Based on an experiment with monetary incentives, we show that people's risk taking behavior is indeed a significant determinant of their time discounting behavior: Greater departures from linear probability weighting predict a stronger decline in impatience on the level of individual behavior.
The Austrian Social Security Database (ASSD) is a matched firm-worker data set, which records the labor market history of almost 11 million individuals from January 1972 to April 2007. Moreover, more than 2.2 million firms can be identified. The individual labor market histories are described in the following dimensions: very detailed daily labor market states and yearly earnings at the firm-worker level, together with a limited set of demographic characteristics. Additionally the ASSD provides some firm related information, such as geographical location and industry affiliation. This paper is a short description of this huge data base and intended for people using this data in their own empirical work.
Momentum in developed countries' stock market index returns can be exploited to form portfolios of excess returns on foreign currencies as relatively high past foreign stock market returns signal a foreign currency appreciation. Two risk factors extracted from the stock index momentum based currency portfolio returns explain more than 80 percent of their cross-sectional variation. In contrast to currency risk factors constructed from forward discount sorted currency portfolios, these risk factors are not related to business cycle or liquidity risk. But high currency risk premia are associated with relatively deep financial integration and a high level of risk sharing.
This paper analyzes a model of oligopolistic competition with ongoing investment. It incorporates the following models as special cases: incremental investment, patent races, learning-by-doing, and network externalities. We investigate circumstances under which a firm with low costs or high quality will extend its initial lead through further cost-reducing or quality-improving investments. In many commonly-studied oligopoly games, such investments are strategic substitutes. We derive a new comparative statics result that applies to games with strategic substitutes, and we use the result to derive conditions under which leading firms invest more than lagging firms. We show that the conditions are satisfied in a variety of commonly-studied oligopoly models. We also highlight plausible countervailing effects from two distinct sources. First, leading firms may find it more costly than others to achieve the same increment to their state. This force is particularly salient inmany models of patentn races, where firms make research investments in an attempt to find a new technology that delivers a given level of cost or quality. Second, countervailing effects may arise in dynamic games with more than two firms are sufficiently patient.
Die Verhandlungen innerhalb der OECD zu einem multilateralen Abkommen ueber Investitionen (MAI) sind gescheitert. Damit werden Direktinvestitionen gegenwaertig weiterhin durch bilaterale Vertraege und durch einige wenige multilaterale Abkommen geregelt. In Zukunft ist jedoch weiterhin damit zu rechnen, daß diese durch ein allgemeines Rahmenwerk nach Vorlage des MAI ersetzt werden. Der vorliegende Aufsatz erlaeutert zunaechst die bestehenden multilateralen Rahmenbedingungen der WTO und der OECD. Anschließend werden die wesentlichen Inhalte des Vertragsentwurfs zum MAI vorgestellt und aus oekonomischer Sicht diskutiert. Ich komme zu der Einschaetzung, daß in einem zukuenftigen Investitionsabkommen (i) wettbewerbspolitische Inhalte, (ii) Ausnahmeregeln in bezug auf wenig industrialisierte Laender und (iii) ein differenzierter Investitionsbegriff enthalten sein sollten. Als Forum fuer ein multilaterales Investitionsabkommen bietet sich die WTO an.
This paper examines costs in the Swiss nursing home industry, an issue of concern to Swiss policy makers because of the explosion of elderly care costs and the aging of the population. The paper considers estimation of a translog cost function employing panel data for a sample of 36 nonprofit nursing homes operating in Ticino, a canton of Switzerland, over the period 1993-1995. Using a set of dummy variables quality differences are considered. The results of this analysis indicate the existence of economies of scale for most output levels.
This paper analyzes economic fluctuations in an overlapping generations economy with productive capital in which random shocks in aggregate productivity are present. Under specific assumptions we obtain an explicit solution of the model. Applying random dynamical systems theory, we can prove that the long-run behavior of the economy is uniquely described by an asymptotically stable random fixed point. The statistical properties of the aggregates output, consumption, capital stock, and real wage are investigated numerically. We find that our artificial economy displays several real world business cycle phenomena.nn
This present paper analyzes an energy tax reform that exempts the energy-intensive export sector from paying the energy tax and uses the additional revenue to cut existing taxes in all sectors. To that end, a two sector two factor model of an open economy that is small on the import side but not on the export side is applied. Within this model, an equivalence between a tax reform with and without exemption of the export sector is derived. The equivalence occurs because in both tax schemes the tax burden is shifted through an increasing producer price of labor from the domestic to the foreign household.
According to the widely used Managerial Power Model, a higher hierarchical position with associated higher power leads to higher compensation. In contrast, the Compensating Wage Differentials Model argues that there is a non-positive relationship between positional power and total compensation. Both power and income yield utility and in equilibrium managers are prepared to trade-off the two elements. The two opposing propositions are tested using a large survey data set from Switzerland. The results suggest that power positions do not yield higher compensation. Rather, there is a non-positive relationship between power position and compensation, if one takes into account all relevant factors influencing total compensation.
"Employees are motivated intrinsically as well as extrinsically. Intrinsic motivation is crucial when tacit knowledge in and between teams must be transferred. Organizational forms enable different kinds of motivation and have different capacities to generate and transfer tacit knowledge. Since knowledge generation and transfer are essential for a firm’s sustainable competitive advantage, we ask specifically what kinds of motivation are needed to generate and transfer tacit knowledge, as opposed to explicit knowledge."
