Empirical evidence of a positive inflation premium being incorporated into stock prices

This study demonstrates that in contrast to prior research findings on short-term stock returns, long-term stock returns are positively correlated with inflation. In addition, within the context of a more complete explanatory model, long-term stock returns are found to be negatively related to changes in long-term interest rates and negatively related to beginning price to earnings ratios. The significance of these variables in explaining almost all the time series variation in long-term stock returns demonstrates that changes in stock values are well explained by theory.     

Degrees of tax indexation and nominal interest rates: Effects of inflation on incentives to save and invest

This paper examines the effects of inflation expectations on nominal interest rates, and incentives to save and invest under partial and complete tax indexation schemes. One would expect that a partially indexed structure would be better than a non-indexed system. However, this is not the case—it reduces the adverse effects of inflation on the incentives to save, but accentuates them on the incentives to invest. Moreover, a change from a non-indexed tax structure to a fully-indexed structure will, ceteris paribus, lead to lower equilibrium interest rates, whereas a switch to a partially indexed system will imply higher rates.

Environmental Certification and Technical Efficiency: A Study of Manufacturing Firms in India

Obtaining environmental certification (such as the ISO-14,001) has become a status symbol for adopting greener practices for the corporate sector in emerging economies. Such certification can help improve the global visibility of firms and is mandated in international trade. This paper attempts to examine the impact of such certifications on technical efficiency of firms belonging to the manufacturing sector in India. In analyzing the impact of ISO Certification on technical efficiency, this paper uses data from the CMIE Prowess from 2007 to 2012. In the first step, the paper estimates technical efficiency for the sample firms and then examines the determinants of inter-firm differences in technical efficiency using firm specific characteristics. The results of this study conclude that there are substantial inter-firm differences in technical efficiency and they are systematically different based on firm age, firm size, debt capital, MNE affiliation, and ISO certification. ISO certification, especially maintaining the standards associated with it, turned out to be an important factor in making the firms achieve higher technical efficiency. In addition, the results of this study also confirm that firms that are ISO certified and doing R&D are better off in technical efficiency as compared to others.     

The market-adjusted investment performance of ADR IPOs and SEOs

Initial public and seasoned equity offerings of American depositary receipts (ADRs) yield significantly positive market-adjusted returns both in early trading and over the longer run. This is in sharp contrast with the long-term performance of initial public offerings and seasoned equity offerings of common stocks in general. In addition, ADRs from emerging markets outperform those originating from developed countries, and those listed on the New York Stock Exchange generate higher after-market returns than those trading on the American Stock Exchange or the National Association of Security Dealers Automated Quotation System.     

Further developments in estimation of the largest mean ofK normal populations

We revisit the bounded maximal risk point estimation problem as well as the fixed-width confidence interval estimation problem for the largest mean amongk(≥2) independent normal populations having unknown means and unknown but equal variance. In the point estimation setup, we devise appropriate two-stage and modified two-stage methodologies so that the associatedmaximal risk can bebounded from aboveexactly by a preassigned positive number. Kuo and Mukhopadhyay (1990), however, emphasized only the asymptotics in this context. We have also introduced, in both point and interval estimation problems,accelerated sequential methodologies thereby saving sampling operations tremendously over the purely sequential schemes considered in Kuo and Mukhopadhyay (1990), but enjoying at the same time asymptotic second-order characteristics, fairly similar to those of the purely sequential ones.     

Random walks,cointegration, and the transmission of shocks across global real estate and equity markets

This article presents tests of the random walk hypothesis for the U.S. and world commercial real estate markets along with the world stock market through utilizing appropriate market indices. The augmented Dickey-Fuller and Phillips-Perron unit root tests and Cochrane variance ratio test find each of these markets to exhibit random walk behavior. In addition, Johansen-Juselius cointegration tests reveal that the three markets are not cointegrated. The vector autoregressive model shows little or no predictive power in explaining the variation in monthly returns. The generalized impulse response functions suggest that shocks stemming from one market are quickly disseminated to the other markets within two months. (JEL G14, G15)

Modelling safety of gantry crane operations using Petri nets

Being a powerful tool in modelling industrial and service operations, Petri net (PN) has been extremely used in different domains, but its application in safety study is limited. In this study, we model the gantry crane operations used for industrial activities using generalized stochastic PNs. The complete cycle of operations of the gantry crane is split into three parts namely inspection and loading, movement of load, and unloading of load. PN models are developed for all three parts and the whole system as well. The developed PN models have captured the safety issues through reachability tree. The hazardous states are identified and how they ultimately lead to some unwanted accidents is demonstrated. The possibility of falling of load and failure of hook, sling, attachment and hoist rope are identified. Possible suggestions based on the study are presented for redesign of the system. For example, mechanical stoppage of operations in case of loosely connected load, and warning system for use of wrong buttons is tested using modified models.
