This paper discusses the impact of income transfers between consumers of a monopoly. In this context, redistributing the incomes could induce an increase of the demand elasticity which leads to a lower monopoly price, beneficial to any consumer. Under mild assumptions on the demand function, we prove the existence of a transfer maximizing the market coverage which remains advantageous for any contributing consumer. It is proved that the producer is also better off. Then the transfer is Pareto-improving. In the linear demand case, analytical results are found. Extensions to Cournot oligopoly and natural monopoly pricing are considered.

Abstract This paper investigates salary functions as used in the valuation of pension plans. Pension actuaries as well as researchers in actuarial science may find many of the ideas in this article useful. The main conclusion of this paper is that salary functions, as derived from the parametric models, yield gains and losses that can be quite small and, in some cases, less variable than nonparametric methods. This paper starts by defining the salary function as an accumulation function based on inflation and merit. Next, we investigate traditional estimation methods in the context of this definition. We then present a parametric age-based model for the salary function and compare it with a parametric service-based model. Finally, we apply real pension plan data to derive age-and service-based salary functions and, through the use of two funding methods, investigate how these salary functions affect salary gains and losses. 相似文献

The strategic decision-making of male and female small businesspersons and entrepreneurs has been investigated in prior research, but the findings are mixed. This article reports on a gender comparison testing of the Entrepreneurial Strategy Matrix, a situational model which suggests strategies for new and ongoing ventures in response to the identification of different levels of venture innovation and risk. A national sample of 184 small firm owers (59 percent male/41 percent female) was tested. Results indicate that there are no significant gender differences in venture innovation/risk situation or in strategies chosen by business owners. Male respondents did indicate a higher overall satisfaction with venture performance than did females. 相似文献

The aim of this work is to advocate the use of multifractional Brownian motion (mBm) as a relevant model in financial mathematics. mBm is an extension of fractional Brownian motion where the Hurst parameter is allowed to vary in time. This enables the possibility to accommodate for varying local regularity, and to decouple it from long‐range dependence properties. While we believe that mBm is potentially useful in a variety of applications in finance, we focus here on a multifractional stochastic volatility Hull & White model that is an extension of the model studied in Comte and Renault. Using the stochastic calculus with respect to mBm developed in Lebovits and Lévy Véhel, we solve the corresponding stochastic differential equations. Since the solutions are of course not explicit, we take advantage of recently developed numerical techniques, namely functional quantization‐based cubature methods, to get accurate approximations. This allows us to test the behavior of our model (as well as the one in Comte and Renault) with respect to its parameters, and in particular its ability to explain some features of the implied volatility surface. An advantage of our model is that it is able both to fit smiles at different maturities, and to take volatility persistence into account in a more precise way than Comte and Renault. 相似文献

Markets are incomplete when the assets available to the agents do not span the space of future contingencies. In that case, competitive equilibria on the markets for assets and commodities fail (generically) to be constrained efficient. Pareto‐superior allocations can be implemented through price/wage rigidities and quantity constraints. However, nominal rigidities are conducive to multiple equilibria, implying endogenous macroeconomic uncertainties that compound the primitive (exogenous) uncertainties. This paper defines a temporary general equilibrium for which there exists a set of equilibria defining an inflation – unemployment locus. Various policy implications are drawn, with relevance to the current crisis. 相似文献

In line with self‐determination theory (Deci & Ryan, 2000), this study aims to determine the influence of different contents and motives of career aspirations, together with objective career success, on subjective career success and well‐being. Moreover, it aims to verify if psychological need, satisfaction, and frustration play a mediating role in these relationships. Results suggest that the pursuit of some aspirations and the underlying motives for their pursuit are more beneficial. Aspiration contents, and aspiration motives, together with objective career success, influence subjective well‐being and subjective career success, in part because they satisfy or frustrate psychological needs. This study brings together two fields of research evolving in parallel—career and life aspirations— to shed new light on both of them. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd. 相似文献

Scenario construction has been the method used in France in a number of studies that relate to regional development planning problems. This article describes how this peculiarly French interpretation of the method is built upon an assessment of a system of elements and their relationship—which forms the dynamic base—and hypotheses concerning external restraints. The progression in such a scenario is developed largely from the consideration of qualitative elements, and images of the future can then be worked out at cross-sections in time. In this way, trend scenarios reveal what is unacceptable and encourage the study of alternative developments. 相似文献
