This paper proposes a concrete theoretical foundation and a new modelling framework that attempts to tackle the issue of market/liquidity risk and economic-capital estimation at a portfolio level by combining two mutual asset market/liquidity risk models. In essence, this study extends research literature related to the assessment of the asset market/liquidity risk by providing a generalized theoretical modelling underpinning that handle, from the same perspective, market and liquidity risks jointly and integrate both risks into a portfolio setting without a commensurate increase of statistical postulations. As such, we argue that market and liquidity risk components are correlated in most cases and can be integrated into one single market/liquidity framework that consists of two interrelated sub-components. The first component is attributed to the impact of adverse price movements and is modelled based on the concept of liquidity-adjusted value-at-risk framework, while the second component focuses on the risk of variation in transactions costs due to the bid-ask spreads and it attempts to measure the likelihood that it will cost more than expected to liquidate the asset position. As such, the model comprises a new approach to contemplating the impact of time-varying volatility of the bid-ask spread and its upshot on the overall asset market/liquidity risk. The modelling framework can be constructive for financial service industries in emerging-economies and particularly in reinforcing rational economic-capital allocation in light of the aftermaths of the sub-prime financial crisis. 相似文献

This paper presents an analysis of the way the Austrian theory of institutions evolved from Menger’s main works. It also tries
to advance the idea that the economics of institutions, when it deals with the emergence and evolution of rules and norms
from interacting individuals, is inspired by Menger’s work and more generally by the Austrian analysis of the emergence and
evolution of institutions. Recent works in the economics of institutions build on this earlier Austrian work to make it more
formalized and testable.

Abstract . In the Dixit-Stiglitz model of monopolistic competition, entry of firms is socially too small. Other authors have shown that excess entry is also a possibility with other preferences for diversity. We show that workers' rents also contribute to explain excess entry through a general equilibrium mechanism. Larger wages indeed raises the aggregate earnings and firms sales and profits, which entices too many firms to enter. We discuss the possibility of over-provision of varieties by comparing the equilibrium to unconstrained and constrained social optima and to other regulatory frameworks where wages are not controlled. 相似文献

This paper is organized as follows: first, we show that the reference to the notion of group selection is coherent with the
other parts of Hayek’s thought. Second, we develop the idea that recent works in terms of the emergence and evolution of social
norms corroborate in part Hayek’s theses in this domain. Finally, we put to the fore some drawbacks in Hayek’s approach and
propose means to solve them.

We propose a new way to locate the comparative advantages of two economies linked by international trade. We construct a competitive benchmark based only on the fundamentals of the two economies: endowments, preferences and technologies. The direction of trade is endogenously determined by a linear program with an input-output core. The factor contents of that trade are compared with factor endowments to test the Heckscher-Ohlin model in the presence of different technologies and preferences. We can also evaluate the gains of free bilateral trade. The model is applied to a customs union between Europe and Canada. The Heckscher-Ohlin factor abundance specialization hypothesis is supported by the data. 相似文献

This paper examines the generalization of the regulated production function. It characterizes the set of admissible regulatory
constraints that are compatible with the existence of a regulated production function in a sufficiently weak framework to
encompass the usual rate-of-return constraints à la Averch and Johnson and value constraints. 相似文献

Inthis paper we develop a new method, based on generalized inverse,to recover the first derivatives of the production function.This allows us to retrieve returns to scale, technological progressand, in a dynamic setting, a measure of the adjustment cost.The method is general and systematic and it applies in caseswhere the traditional method does not. It is especially relevantwhen examining dynamic models or regulated firms. 相似文献

High transaction costs are detrimental to the efficient operation or existence of markets for inputs and outputs. The cost of information and the costs associated with the search for trade partners, the distance to formal markets and contract enforcement are likely to influence the marketing of food crops. This study hypothesises that the level of income generated from food-crop sales by small-scale farmers in the Impendle and Swayimana districts of KwaZuluNatal is influenced by transaction costs and certain household and farm characteristics. Regression analysis shows that the depth of marketing methods is significantly influenced by transaction cost proxies, such as cooperation with large commercial farmers and ownership of means of transport. Results from a block-recursive regression analysis show that the level of crop income generated is determined by the depth of marketing methods, the size of allocated arable land and off-farm income. Households with lower transaction costs, sizeable allocated land and off-farm income can be expected to generate higher income from food crops. Investment in public goods such as roads, telecommunications and an efficient legal system (to uphold commercial contracts), as well as farmer support services (input supply, extension, marketing information and research), would probably raise farm and non-farm income by reducing transaction costs. This would increase the effective demand for locally produced goods and services, thus contributing to rural employment and livelihoods within rural communal areas. 相似文献
