The Exchange Rate and Inflation in Argentina: A Classical Critique of Orthodox and Heterodox Policy Prescriptions

In this paper we present an alternative framework to neoclassical theory of international trade and exchange rate determination. Our model, inspired in the classical tradition, provides support for the assertion that an exchange rate policy aiming to improve national competitiveness and to bring about a sustained trade surplus is a viable option. In fact, the success of this strategy does not depend on the effectiveness of monetary sterilization —as many argentinean heterodox authors claim— but on the ability to overcome the boundaries imposed by the evolution of the domestic wage rate and the potential emergence of competitive devaluations. In the particular case of Argentina, the introduction of export taxes on land-intensive commodities, in which the economy has absolute advantages, brings an additional policy tool that can make both the exchange rate target and the workers claims consistent.     

Attracting Long‐Term Shareholders

Corporate CEOs often say they don't hear enough from shareholders about strategic issues related to long‐term value creation. At the same time, they claim to hear with predictable regularity from short‐term investors about their success (or failure) in hitting consensus earnings targets. But as the authors of this article begin by noting, there is mounting evidence that companies get the shareholders they deserve—that companies that provide quarterly earnings guidance and otherwise focus investor attention on near‐term earnings targets tend to attract more transient investors. The authors go on to argue that companies with a compelling long‐term vision can expect to benefit not only from more farsighted managerial decision‐making, but also from building a base of longer‐term investors who share management's view of success, and how it can and ought to be achieved. Such a shift in strategic focus and disclosure toward longer‐run performance creates a virtuous cycle—one in which companies that gain the interest and backing of investors with longer horizons end up reinforcing management's confidence to undertake value‐adding investments in their company's future. Even if most companies can't pick their shareholders, they can develop an investor engagement strategy designed to attract long‐term investors. In this article, the chairman and president of FCLTGlobal outline the underlying strategy behind long‐term investor relations and the four key components of such an approach.     

Adoption and abandonment of irrigation technologies

Adoption and abandonment processes are analyzed for seven irrigation technologies. A procedure is developed to estimate the technology cycle and applied to data available for citrus groves in several regions of Israel, and Gaza. The technology cycle was used to estimate diffusion-abandonment patterns for several irrigation technologies that have been abandoned. Results suggest that the technology cycle is unique to each technology and similar in length for all regions. Results predict the year of full abandonment of each technology. For modern technologies still in the diffusion phase, a logistic equation was fitted to the aggregated data. Results suggest that diffusion is significantly affected by economic variables such as water price, crop yield price, and subsidy for irrigation equipment. Use of the estimated equations for policy purposes suggest that water price and subsidy for irrigation equipment can be used to control the diffusion process (speed and ceiling) of the irrigation technologies.     

Do physician incentives affect hospital choice? A progress report

The US health reforms of March 2010 introduced new provisions for physicians providing Medicare and Medicaid services to be given financial incentives to control costs. Physician payment mechanisms generating similar incentives are currently used by some health maintenance organizations in California. We describe an ongoing research project in which we investigate physician responses to these payment schemes. The question is whether patients whose physicians have incentives to control hospital costs are admitted to lower-priced hospitals than other patients, all else equal. We provide an initial analysis of California hospital discharge data from 2003, documenting evidence consistent with this hypothesis.     

Measuring knowledge production of an agricultural research system

Agricultural research that increases knowledge is an important component of agricultural productivity and development. This paper focuses on understanding and formulating the interactions among factors involved in the knowledge production process. A conceptual mode of research input-output relationships is developed based on the existing literature. These relationships are estimated based on cross-sectional time-series data for the public research system in Israel. Research resources (inputs) such as direct cost and senior scientific manpower were found to extend knowledge production, while resources such as junior researchers and technicians were found to be nonsignificant. Use of the estimated functions for forecasting and control of agricultural development is also illustrated.     

Duality theory for robust utility maximisation

In this paper, we present a duality theory for the robust utility maximisation problem in continuous time for utility functions defined on the positive real line. Our results are inspired by – and can be seen as the robust analogues of – the seminal work of Kramkov and Schachermayer (Ann. Appl. Probab. 9:904–950, 1999). Namely, we show that if the set of attainable trading outcomes and the set of pricing measures satisfy a bipolar relation, then the utility maximisation problem is in duality with a conjugate problem. We further discuss the existence of optimal trading strategies. In particular, our general results include the case of logarithmic and power utility, and they apply to drift and volatility uncertainty.

     

On the Samuelson–Etula Master Function and the capital controversy

Abstract

The paper addresses the ambiguity that surrounds the conception of capital and its role in neoclassical price-and-distribution theory. The difficulties encountered in the various attempts to define the marginal product either of capital or of a capital good are recalled and the conclusion is drawn that neither concept appears theoretically sound. This historical reconstruction is combined with critical discussion of the recent attempt by Paul Samuelson to determine income distribution by means of the “Master Function”, a device previously developed and presented by Samuelson himself with Erkko Etula, and its “non-neoclassical” marginal products. Rather than the existence of a continuum of alternative technical possibilities, this construction assumes the simultaneous use of a discrete number of methods of production for the same commodity. Even though each technique employs the inputs in fixed proportions, the coexistence of various techniques permits the full employment of an arbitrarily given vector of input endowments. As is shown here, however, the coexistence of methods required for the differentiability of the Master Function can take place, if heterogenous capital goods are used in production, neither in the case with stationary relative prices nor in the non-stationary Arrow–Debreu framework.     

Unbundling democracy: Political rights and civil liberties

Much recent political economy and political science literature views democracy in terms of political rights. This view, often referred to as electoral democracy, is particularly pronounced in the empirical literature. We reincorporate the role of civil liberties, which are at the core of modern democracy, in two ways. We identify four fundamental sources of potential differences in the evolution of political rights and civil liberties. We present systematic, robust and varied empirical evidence on the direct impact of two of these potential sources of differences using cross-national panel data and accounting for the modernization hypothesis. We obtain two noteworthy empirical results: civil liberties exhibit greater persistence than political rights in affecting subsequent outcomes; and, our main result, civil liberties are complementary to political rights when affecting subsequent outcomes, while the reverse is not the case. Consequently, one must incorporate civil liberties as a determinant of electoral democracy. More generally, both dimensions must be considered to understand the setbacks recently experienced by many democracies, despite their holding of free and fair elections.     

Cooperative Management of Groundwater Resources in the Presence of Environmental Externalities

This paper investigates how cooperation among users can achieve a better management of groundwater in the presence of environmental externalities. Cooperation allows users to internalize the damages caused by their activities and reduce extractions. The paper develops a game theoretical framework to assess the value of cooperation in an aquifer that is divided into three sub-aquifers that are being overly exploited. Two types of externalities are modeled: first, water extractions in each sub-aquifer impact water levels in neighboring sub-aquifers (extraction externality). Second, the three sub-aquifers are also connected to an ecosystem and thus decisions in each sub-aquifer affect the health of the ecosystem (environmental externality). A cooperative game theory model is applied. The model empirically shows how the uncontrolled extractions in each sub-aquifer affects neighboring groundwater users but also cause severe impacts to the linked ecosystem. The model is tested empirically in one of the most important aquifers in Spain, the Eastern la Mancha aquifer. The results illustrate how both extraction and environmental externalities interact in affecting the likelihood of cooperation among the users. The paper estimates the value of cooperation and its stability with and without the environmental externality.     

Edgar Allan Poe's riddle: Framing effects in repeated matching pennies games

Framing effects have a significant influence on the finitely repeated matching pennies game. The combination of being labelled “a guesser,” and having the objective of matching the opponent's action, appears to be advantageous. We find that being a player who aims to match the opponent's action is advantageous irrespective of whether the player moves first or second. We examine alternative explanations for our results and relate them to Edgar Allan Poe's “The Purloined Letter.” We propose a behavioral model which generates the observed asymmetry in the players' performance.
