Characterization of the turnpike property of optimal paths in the aggregative model of intertemporal allocation

The present paper provides a complete characterization of the turnpike property of optimal paths in the (reduced form) aggregative model of intertemporal allocation. The characterization allows one to identify precisely the bifurcation point between globally stable and cyclical long-run optimal behavior. The complete characterization result is used to evaluate several sufficient conditions for global asymptotic stability of optimal paths that have been proposed in the published literature. It is also used to examine sufficient conditions for the emergence of competitive equilibrium cycles in two-sector models.     

Intertemporally dependent preferences and optimal dynamic behavior

We study a model of optimal dynamic behavior in which the intertemoral preferences preserve the time additively separable framework of Ramsey models, while exhibiting Edgeworth–Pareto complementarity between consumption in adjacent periods. We identify economic environments in which global optimal dynamics under intertemporal complementarity exhibits persistent fluctuations even though the misspecified Ramsey-type theory, under the intertemporal independence assumption, predicts monotone convergence.     

Efficient and optimal programs when investment is irreversible: A duality theory

An attempt is made in this paper to formulate a satisfactory duality theory of efficient and optimal programs in intertemporal models with irreversible inveatment. The introduction of the constraint that depreciated capital stock cannot be used for present consumption makes the meaningful choice and interpretation of dual variables a more difficult problem, as is pointed out by means of an example. A new definition of a competitive program is introduced, and this is seen to lead to useful characterizations of efficient and optimal programs.     

Share Ribs and Income Distribution*

The connection between changes in commodity prices and the distribution of income is a question of active interest since the 1941 Stolper-Samuelson Theorem. In higher dimensions results are obtained only if structure is imposed. Here we assume that each of n-industries is alike in the shape of the profile (rib) of distributive factor shares with a permutation of factor numbering such that industry n is most intensive in factor n. Such a structure reveals either a strong version of the Stolper Samuelson Theorem or a Neighborhood oscillation pattern depending on the shape of the share ribs.     

India's Evolving Economic Model:

Abstract Over the course of the past 50 years, India has developed as a stable economy. Economic policies of the Indian government have guided and shaped India into a mixed economy. Political stability has been a significant factor in this process. The United States and European economic and political systems had a significant impact on evolution of India's economic model. Financial and economic reforms since 1991 have accelerated the pace of change toward an open market economy both in its internal operations and in its linkages with the global markets. India's economic future is now promising as it moves forward on its unique path of economic policy.     

Do consumers view the nutrition facts panel when making healthfulness assessments of food products? Antecedents and consequences

Consumer use of the Nutrition Facts Panel (NFP) is an important topic of interest to researchers and public policymakers. Studies conducted in the United States and elsewhere find high levels of self-reported use of the NFP or its equivalent. However, data from self-reports may inflate estimated NFP use due to social desirability problems. Utilizing data from an online experiment, we examine whether consumers choose to view the NFP when assessing the nutritional properties and disease-fighting abilities of foods. We also examine the antecedents of NFP-viewing behavior and its implications for the accuracy of healthfulness judgments and the potential for overgeneralization. We conclude with a discussion of the public policy implications of our results and point to directions for future research.     

Consumer Skepticism of Claims in Food Ads vs. on Food Labels: An Exploration of Differences and Antecedents

Considerable evidence shows that consumers are skeptical of advertising, that is, have a tendency to doubt the truth of advertising claims. The main focus of our paper is to explore, in the context of food products, whether this typically high level of skepticism is also exhibited for product labels. In addition, we look at consumer skepticism associated with health claims in food ads and labels as well as with the Nutrition Facts Panel on food packages. Finally, we examine some individual difference factors that might influence consumer skepticism. We report the results of a large‐scale survey designed to explore these issues, and we discuss the implications of our findings for public policy and future research.     

Smallest Meaningful Pay Increases: Field Test,Constructive Replication,and Extension

The authors extend prior literature by examining, in two distinct field settings, smallest meaningful pay increases (SMPIs) in terms of magnitude, behavioral intention, and affective reactions. In Study 1, a two‐wave study of 177 employees of a university medical center in the United States, the authors find stable thresholds of about 5.0 percent for positive reactions to pay increases (magnitude [5.4 percent], behavioral intentions [4.2 percent], and affective reactions [5.6 percent]). In Study 2, a sample of 495 university employees in Finland, the authors also find stable but slightly higher thresholds of about 8 percent for behavioral intentions (8.4 percent) and positive affective reactions (7.2 percent) to pay increases. They also find threshold effects of ?5.7 percent for behavioral intentions and ?5.8 percent for negative affective reactions in response to restricted future pay increases levied in the transition to a new pay system. Discussion of the results centers on pay raise administration and future research regarding implied and direct pay reductions. © 2015 Wiley Periodicals, Inc.
