We study a model of informed principal with private values where the principal is risk neutral and the agent is risk averse.
We show that the principal, regardless of her type, gains by not revealing her type to the agent through the contract offer.
The equilibrium allocation transfers some ex-ante risk from one type of agent to the other. Despite the increase in the principal's
surplus, allocative efficiency does not necessarily improve.

Abstract
The problem of numerically pricing credit default index swaptions on a large number of names is considered. We place ourselves
in a stochastic intensity framework, where Ornstein-Uhlenbeck-type correlated processes are used to model both firms’ distance
to default and a macroeconomic state variable. Here the default of the firms’ follows the reduced-form approach and the (random)
intensity of the default depends on the behavior of the diffusion processes. We propose here a numerical method based on both
a Monte Carlo and a deterministic approach for solving PDEs by finite differences. Numerical tests demonstrate the efficiency
and the robustness of the proposed procedure. 相似文献

In the organizational career management literature, scholars have focused on career management policies, with little attention given to practices that can vary within organizations. And despite its recognized importance, research on the role of leaders in the career management process is also scant. In this study, we investigate the effects of career management practices (OCPs) and leadership career support (LCS) on employee attitudes. Grounded on coping theory, we propose that career support received from line managers can be particularly consequential when OCPs are lacking. We analyze the moderating effects of LCS on the relationship between OCPs and both job satisfaction and turnover intention in a sample of employees from a large Brazilian organization, applying multiple regression analyses. Results showed that OCPs and LCS are positively related to job satisfaction and that OCPs are negatively related to turnover intention. In addition, we confirmed that LCS moderates the relationship between OCPs and both job satisfaction and turnover intention. Finally, we observed that the relationship between OCPs and turnover intention is mediated by job satisfaction. Theoretical and practical implications are discussed. 相似文献

This paper examines empirically the relationship between electricity spot and futures prices, by analysing a decade of data for a set of short term-to-maturity futures contracts traded in the Nordic Power Exchange. It is found that, on average, there are significant positive risk premiums in short-term electricity futures prices. The significance and size of the premiums, however, varies seasonally over the year; whereas it is greatest during winter, it is zero in summer. It is also found that time-varying risk premiums are significantly related to unexpectedly low reservoir levels. Furthermore, before the unprecedented supply-shock that hit the market around the end of year 2002, the risk premiums were related to the variance and the skewness of future spot prices. 相似文献

We introduce the results of a non-parametric estimate of the US wage-Phillips Curve into a simplified version of the model of the wage-price spiral by Flaschel and Krolzig (2008). Making use of Okun’s law, the non-linearity in the wage inflation-employment relation translates into a non-linearity in the so-called ‘distributive curve’ of the economy. Exploiting the observed non-linearity in extending an otherwise standard demand-distribution model (Taylor 2004), we provide a dynamical analysis both in wage-led and profit-led effective demand regimes. In a profit-led scenario, shown to be the empirically relevant case for the US economy, there are two stable equilibria of Goodwin (1967) growth cycle type, identified as a stable depression and a stable boom, and a saddle-path stable equilibrium in between them. Both stable steady states are surrounded by trajectories that cycle counterclockwise around their basins of attraction. The obtained type of growth fluctuations can be verified by a long phase cycle estimation for the US economy using a method developed by Kauermann, Teuber and Flaschel (2008). 相似文献

In 1926 and 1936 Sraff and Keynes attacked the methodological core of traditional economic theory by showing that the premises of partial equilibrium analysis were mutually inconsistent. this paper aims to show that Harrod neglected Sraffa and Keynes's logical arguments, and only admitted that the tacit assumptions under discussion restricted the domain of validityof the theory to special cases: perfect competition and statics. He then proceeded to generalize the theory to imperfect competition and dynamics by applying the principles (but not the instruments) of traditional analysis. The definition of these domains thus aimede at rescuing as mush as possible from the orthodox approach. 相似文献

This paper presents the contributions of Francesco Forte to the measurement of art and cultural goods and services, as I worked with him as his co-author. These contributions range from the valuation of art goods by the art matrix we conceived, to the valuation of the cultural welfare of nations, regions and local communities. Our work also assessed the provision of cultural welfare at the national, regional and local level for the public and non-profit sectors and measured the efficiency and effectiveness of museum bureaucracies. We also studied the profitability of investments in the arts by considering product life cycles, artistic movements and economies. More recently, with Michele Caputo, we focused on the long-run life cycle and success of the movie industry for select countries competing with foreign movie industries and TV entertainment by adopting Caputo’s fractional derivatives theory, which captures the role of past history. Professor Forte and I also developed the Differential Touristic Development Index to measure the effects of art and cultural enterprises as tourist attractions. The most innovative contributions of Francesco Forte to the measurement of the economic value of cultural goods and services demonstrate that it is possible to “measure the unmeasured,” and therein improve public collection of statistical data with the goal of increasing the preservation and valuation of cultural goods and services and highlighting their potential as economic multipliers. 相似文献

We investigate whether in a mixed insurance system, people enrolled into voluntary health care insurance (VHI) substitute public consumption with private (opt out) or just enlarge their private consumption without reducing reliance upon public provisions (top up). We specify a joint model for public and private specialist visits counts, allowing for different degrees of endogenous supplementary insurance coverage. We find evidence of opting out: richer and wealthier individuals consume more private services and concomitantly reduce those services publicly provided through selection into for‐profit VHI. Accounting for VHI endogeneity in the joint model of the two counts is crucial to this conclusion. 相似文献

We study the exploitation of a common groundwater resource, first as a static and then as a differential game, in order to take into account the strategic and dynamic interactions among the users of the resource. We suppose that firms can form coalitions or can decide not to cooperate. The non-cooperation regime is characterized by pumping that lead to depletion of the aquifer; the cooperation preserves the resource. Open-loop and feedback equilibria have been computed and compared in order to characterize the existence of cooperators and defectors in water resources management. 相似文献
