The Corn–Guano Model

The model presented here can be seen as an extension, specifically designed to deal with the issue of exhaustible resources, of the well‐known ‘corn model’. We believe that useful insights are obtained by concentrating on a benchmark case, that of an economy with only one reproducible ‘good’, corn, and only one ‘resource’, guano. The corn–guano model aims at delineating some major issues related to the introduction of exhaustible resources within a post‐Sraffian model. In this paper we concentrate on the dynamics of the price variables. The ultimate goal concerns more generally the treatment of intertemporal economies outside a regular growth path, i.e. it concerns the degree of generality of the post‐Sraffian theory itself.     

Recycling and Landfilling in a Dynamic Sraffian Model: Application of the Corn–guano Model to a Waste Treatment problem

Landfill sites may be regarded as input for a waste treatment process. Considering landfill as an exhaustible resource, we apply a basic corn–guano model to a waste treatment problem. We show how dynamic substitution between landfilling and recycling occurs. Namely, in an early stage, landfill disposal is adopted as waste treatment and a recycling process is not activated. Once an economy faces exhaustion of landfill, a recycling process is activated as a backstop technology. We refer to the possibility that an economy may be unstable after exhaustion of landfill, even if it enjoys stable growth at the early stage.     

A Leibenstein–Hobbes–Walras Model of Sharecropping

Circumstances under which share tenancy may emerge as a socially viable and incentive-compatible system of land-labor exchange are explored in a model incorporating Leibenstein’s nutrition-effort hypothesis, limited substitution possibilities and endogenous distribution. The model provides a Walrasian resolution of the traditional conundrum of production control under sharecropping. It is shown that a pure sharecropp ing equilibrium with tenant control exists when land is relatively abundant though land rent is zero under either a fixed-rent or wage system. With land relatively scarce, a nearly-symmetric equilibrium with landlord control also exists provided workers share income in the presence of unemployment.     

Predator–Prey Model Estimates of the Cyclical Profit Squeeze

This paper extends the empirical literature on the cyclical profit squeeze (CPS) theory of crisis by developing a multivariate model with superior decomposition methods. A structural time series (unobserved components) model with trend and structural VAR components is employed. The VAR captures the dynamic cyclical interaction between unemployment and profit's share of income and is interpreted as a linear version of Goodwin's (1967) predator-prey model. Model extensions incorporate the accumulation process and structural shifts. Estimation results for the US economy are used to sort out the controversial relevance of the CPS in the post-1970 period. It is concluded that the CPS is relevant during the period from 1949 to 1985, but is moderately weakened in the post-1970 period. Inconclusive statistical support for the CPS is found for the post-1985 era.     

A Kaldor–Hicks–Goodwin–Tobin–Kalecki model of growth and distribution

This paper presents a Kaldorian model of growth that incorporates both Kaldor's theory of income distribution and his endogenous technical progress function. Growth is driven by demand‐side forces that induce supply‐side accommodation. The model incorporates Hicksian induced innovation; Goodwin Marxist style labor conflict that affects wage bill division between workers and managers; Tobin inflation effects; and Kalecki monopoly power effects. Unlike the neo‐Kaleckian model, a Kaldorian economy operates at normal capacity utilization. Monopoly power plays a role as a barrier to entry rather than determining the functional distribution of income.     

互联网金融之辨析

2012年以后,在互联网金融将颠覆传统金融的热议中,中国互联网金融发展进入了高峰期,一些地方政府甚至将其列为发展的重点项目.本文认为,互联网金融在概念上有着明显的局限性,在功能上并无颠覆金融的可能,在机制上更多的是利用了中国金融体制机制的缺陷所进行的监管套利,在发展上具有拾遗补缺的作用但难以成为金融的主流运作方式.在互联网金融热潮中,应防止新一轮的金融泡沫产生.

Functional forms of the satisfaction–loyalty relationship

The linear functional form of the effect of customer satisfaction on repurchase intentions may not be adequate under all circumstances; however, we lack a clear understanding of the factors that may drive variation in the functional forms of the satisfaction-loyalty relationship. Building on existing research, the authors consider how the functional form of the effect of satisfaction on repurchase intentions varies across segments formed at the intersection of product categories and customer economic and demographic variables. A comprehensive data set obtained from the sponsors of the Chinese Customer Satisfaction Index provides the input for a flexible cubic regression configuration to model the functional forms. The linear functional form emerges as the most prominent across 972 product-customer segments (51%), followed in frequency by the S-shaped and convex forms and, finally, the inverse S-shape and concave forms. Different product category characteristics, customer economic and demographic variables, and market characteristics moderate the effect of satisfaction on repurchase intentions differently for the linear, quadratic, and cubic terms. This research reveals key resource allocation implications based on the functional forms of the effect of satisfaction on repurchase intentions, as well as strategic segmentation implications related to the varying influence of product category characteristics, customer economic and demographic variables, and market characteristics.     

The Short– and Long–run Performance of New Listings in Tunisia

This study examines abnormal stock market returns of new listings on the Tunisian Stock Exchange. Substantial positive abnormal returns are found on the first listing day and this finding is similar to that obtained in other countries. Subsequent performance is poor and investors who bought shares at the close of trading on the first day would have lost about 22% against the Tunis Stock Exchange index over a three–year period. The possible causes of this are investigated. Among the factors found in the literature that possibly affect the level of long–term performance, only the state of the IPO market, the initial return, the delay in reaching the ‘first market price’ and the size of the firms have significant coefficients. This result is supportive of the traditional fad’s interpretation of long–term underperformance.     

HETEROGENEOUS CAPITAL GOODS AND THE HARROD–BALASSA–SAMUELSON EFFECT

This paper shows that in a world of ‘production of commodities by means of commodities’ there is not an unambiguous relation between the long‐period relative commodity prices and the sectoral total factor productivities. Consequently, the Harrod–Balassa–Samuelson effect is not verified and/or makes no sense.     

A Critique and A Retrieval of Management and the Humanities

The use of literature, and other sources from the humanities, in management education has become more prominent in recent years. But, there is reason to question the ethical justifications by which the marriage of Management and the Humanities is customarily defended. This paper is a critique of Management and the Humanities as it is practiced through the use of literature. By means of a liberal pragmatist kind of criticism, and a case analysis about a hypothetical Grand Theory of Management called Theory R, I draw a sharp distinction between a Management and the Humanities approach that merely confirms conventional truths and a new approach to Management and the Humanities that enables students to grow as what Henry Giroux calls "critical rather than 'good' citizens." I show how this new approach can enable management educators to retrieve the potential of Management and the Humanities to contribute to liberal education.     

New Bilateralism in the Asia–Pacific

This paper reviews recent changes in the geographic pattern of regional trading agreements (RTAs), focusing on examples from the Asia–Pacific area. The general pattern is one of new bilateral agreements combined with a trend towards continentalism. The new trend towards bilateralism can be explained largely by a fear of countries being excluded from their major markets as other countries secure preferential and superior access to these markets. This pattern is creating many intersections between RTAs with consequential multi–tiered preferences and multiple systems of trade rules. Viewed dynamically, however, this pattern may have positive effects on world trade. It mitigates the effects of large continental RTAs and may lead to coalescence or enlargement of RTAs. The paper reviews models which ask the important question as to whether this process will progress all the way to free trade for the world economy.     

Customer Referral Reward–Brand–Fit: A Schema Congruity Perspective

Customer referral programs (CRPs) are widely applied as an effective means to stimulate word‐of‐mouth. While previous research mainly focuses on CRPs’ impact of acquiring new customers, this study introduces referral programs as a strategic brand management tool. In doing so, this article emphasizes what has been largely neglected by scholars: A “recommenders‐perspective.” Guided by two competing theoretical perspectives, this article proposes that the perceived congruity between a reward and the recommended brand is an essential driver of referral program performance outcomes. The results show that rewards that conform to the image of the recommended brand yield more favorable reward attractiveness perceptions. Furthermore, the authors show that reward attractiveness perceptions inevitably affect the brand customers are asked to recommend in exchange for receiving this reward. The research reported here extends the literature on judgmental evaluations resulting from schema‐based processing and provides novel insights into the design of CRPs.     

GENERALIZATION OF THE DYBVIG–INGERSOLL–ROSS THEOREM AND ASYMPTOTIC MINIMALITY

The long‐term limit of zero‐coupon rates with respect to the maturity does not always exist. In this case we use the limit superior and prove corresponding versions of the Dybvig–Ingersoll–Ross theorem, which says that long‐term spot and forward rates can never fall in an arbitrage‐free model. Extensions of popular interest rate models needing this generalization are presented. In addition, we discuss several definitions of arbitrage, prove asymptotic minimality of the limit superior of the spot rates, and illustrate our results by several continuous‐time short‐rate models.
