On the existence of a stationary optimal stock for a multi-sector economy: A primal approach

Using a purely primal approach, we show the existence of a non-trivial stationary optimal stock for a multi-sector economy. Our result generalizes earlier work by dropping the δ-productivity assumption and by replacing the continuity hypothesis on the utility function by upper semicontinuity.     

Pareto optimality and competitive equilibrium in infinite horizon economies

The paper presents a general model of a decentralized economy evolving over an infinite time horizon. Alternative notions of price systems, competitive equilibria, efficiency and optimality are introduced. The main results characterize conditions under which the two fundamental theorems of welfare economics are valid in such a general framework.     

Are non-fundamental equilibria learnable in models of monetary policy?

Recent models of monetary policy can have indeterminacy of equilibria, which is often viewed as a difficulty of these models. We consider the significance of indeterminacy using the learning approach to expectations formation. We employ expectational stability as a selection criterion for different equilibria and derive the expectational stability and instability conditions for forward-looking multivariate models, both without and with lags. The results are applied to several monetary policies.     

US oil companies’ earnings management in response to hurricanes Katrina and Rita

This study examines earnings management by US-based oil companies in the period immediately after the impact of hurricanes Katrina and Rita. We show that large petroleum refining firms – but not the smaller crude oil and natural gas production companies – recorded significant abnormal income-decreasing accruals in the fiscal quarter immediately after the impact of hurricanes Katrina and Rita (Q4 of 2005). In addition, we show that these results are driven by abnormal current accruals. Prior studies show that some firms respond to periods of heightened political scrutiny by recording abnormal income-decreasing accruals (e.g. [Cahan, S., 1992. The effect of antitrust investigation on discretionary accruals: a refined test of the political cost hypothesis. The Accounting Review 67 (1), 77–96; Han, J., Wang, S., 1998. Political costs and earnings management of oil companies during the 1990 Persian Gulf Crisis. The Accounting Review 73 (1), 103–118]). Our results add to this stream of research by examining a political cost-increasing event that occurred after the passage of the Sarbanes–Oxley Act (SOX) of 2002. The results suggest that in the post-SOX period managers continue to engage in income-decreasing earnings management during periods of heightened political cost sensitivity, at least in the case of large petroleum refining firms.     

The Phenomenon of Brand Love: A Systematic Literature Review

Abstract

Brand love is a phenomenon that is experienced by a group of satisfied consumers. The construct brand love is of great importance to academics and practitioners because a group of satisfied customers become loyal customers, thereby reduce several costs and also enhance several marketing activities. Since the research paper of it can be observed that there has been a surge in the number of research publications pertinent to brand love literature. Through this systematic literature review, we comprehensively review seventy six articles pertinent to brand love literature, published in various scientific journals there by presenting the key emergent themes, extensively used methodologies and analysis approaches, key variables observed, dominant theoretical underpinnings and a strategic conceptual framework.     

Value-relevance of pension transition adjustments and other comprehensive income components in the adoption year of SFAS No. 158

In the present study, we examine the value-relevance of pension transition adjustments and other comprehensive income (OCI) components in the initial adoption year of Statement of Financial Accounting Standard (SFAS) 158—Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans. Using a sample of 697 Standard and Poor (S&P) firms with the fiscal year ending on December 31, 2006, we perform several cross-sectional regression analyses to test the value-relevance of transition adjustments and OCI components in presence of various earnings measures. The results indicate that there is a negative relationship between both the level and change in stock returns and the magnitude of pension transition adjustments. We also find earnings measures and some OCI components are significantly associated with stock returns. When analyzed separately, we find our main results are mostly confined to the sample large S&P 500 firms. We do not find any result for the S&P mid-cap and small-cap firms. The overall results suggest the stock market negatively reacts to the adverse impact of SFAS #158 pension transition adjustments on net worth and future cash flows when the impact is substantial in its magnitude in dollar terms. The study further provides useful insight into the information processing by documenting that the market evaluates accounting information more effectively when such information is recognized in the financial statements rather than disclosed only in the financial footnotes.     

Optimal and competitive programs in reachable multi sector models

Summary. We show that in multi-sector optimal growth models, where the technology satisfies a simple reachability condition, infinite horizon programs which satisfy the competitive conditions are optimal. We provide examples of a variety of production models where the reachability condition is satisfied. An example is also provided where the reachability condition is not satisfied and there are competitive programs which are not optimal. The results of the paper are of interest from the standpoint of decentralization in intertemporal economies. Received: March 24, 1994; revised version: October 10, 1998     

Modelling risk factors for fatal pedestrian crashes in Kolkata,India

Abstract

In developing countries, pedestrian safety is an issue of major concern. Although an extensive body of literature is available on the identification of elements related to the pedestrian’s risk; the studies are primarily conducted in urban areas of developed countries. The findings from these studies may only be partially relevant to the cities of an emerging country such as India. The present study analyzes historical crash records obtained from the “Kolkata Police” and identifies the risk factors at the road network level for the hazardous corridors posing a high risk to the pedestrians. The study findings reveal that pedestrians’ fatalities at intersections are associated with a high vehicular volume, higher pedestrian-vehicular interaction, high approach speed, overtaking tendency of vehicles, certain land-use type, encroachment of footpath, inadequate sight distance, inaccessible pedestrian crosswalk, wider minor carriageway, the absence of a pedestrian signal head, and lack of enforcement. On the other hand, the models outcomes reveal that pedestrians’ fatalities at midblock road segments are associated with low pedestrian volume, high approach speed, overtaking tendency of the vehicle, encroachment of footpath, on-street parking, wider road width, certain land-use type, inadequate sight distance, insufficient lighting, and inadequate pavement markings.     

The relationship between conditional value at risk and option prices with a closed-form solution

Options and CVaR (conditional value at risk) are significant areas of research in their own right; moreover, both are important to risk management and understanding of risk. Despite the importance and the overlap of interests in CVaR and options, the literature relating the two is virtually non-existent. In this paper we derive a model-free, simple and closed-form analytic equation that determines the CVaR associated with a put option. This relation is model free and is applicable in complete and incomplete markets. We show that we can account for implied volatility effects using the CVaR risk of options. We show how the relation between options and CVaR has important risk management implications, particularly in terms of integrated risk management and preventing arbitrage opportunities. We conduct numerical experiments to demonstrate obtaining CVaR from empirical options data.     

Customer portfolio composition and customer equity feedback effects: Student diversity and acquisition in educational communities

Researchers in marketing have long recognized that current populations of customers can influence the behavior of prospective customers. This paper draws on existing marketing theories to empirically examine how changes in student body demographic segments influence future demand for MBA programs. Using a longitudinal analysis of data spanning 18 years, we find that higher proportion of female students leads to significant increases in future applications. This implies a marketing rationale for business schools in encouraging gender diversity. In contrast, we find evidence of prejudice towards minority and international students among business school applicants. We discuss the results of the analysis in the context of the current affirmative action debate and changes in demographic trends.
