Ratio cum product method of estimation

Summary In this paper methods of estimation which may be considered as combination of ratio and product methods have been suggested. The mean square errors of these estimators utilizing two supplementary variables are compared with (i) simple unbiased estimator (p=0), (ii) usual ratio and product methods of estimation (p=1) and (iii) multivariate ratio and multivariate product estimators (p=2), wherep is the number of supplementary variables utilized. Conditions for their efficient use have been obtained for each case. Extension to general case ofp-variables has been briefly discussed. A new criteria for the efficient use of product estimator have been obtained.     

THE IMPACT OF BEQUESTS ON LIFETIME WEALTH ACCUMULATION: AN ECONOMETRIC STUDY OF TWO GENERATIONS OF RURAL HOUSEHOLDS IN INDIA

Using retrospective data on bequest receipts and wealth over two generations of rural Indian households, we have estimated the effect of bequest receipts on the lifetime wealth accumulation of recipients. We exploit the availability of data on two generations of the same household by estimating a family fixed effects model that controls for unobserved, intergenerationally-persistent household endowments. Our results suggest an adverse impact of bequest receipts on the wealth accumulation of recipients. This effect is much more negative for the current generation of household heads than for the previous generation, indicating that the disincentive effects associated with bequest receipts have increased substantially over a generation. Such disincentive effects are consistent with the commonly-observed phenomenon of "regression to the mean." The empirical results also show that the positive association between schooling and wealth accumulation has strengthened substantially over the course of a generation, implying rising returns to schooling.     

Design of quench system for runaway reactions using bench-scale equipment

Runaway chemical reactions are a potential problem in many sectors of the chemical industry. The typical hazard scenario involves a batch (or semi-batch) chemical reaction where, due to an operator error or instrument failure, the reaction temperature begins to accelerate rapidly. The rise in temperature is, of course, accompanied by a rise in pressure and in order to prevent vessel rupture, some means of protection must be provided. The common approach to overpressure protection in the industry is to fit a relief device to the reactor vessel in question; the device opens at a predetermined pressure and, provided it is sized correctly, the maximum pressure can be kept within acceptable limits. The Design Institute for Emergency Relief Systems (DIERS), organized through the auspices of the AIChE [1], undertook several years of research to develop the methodology for the sizing of relief systems to cope with runaway reactions. The emphasis in industry has changed so considerably since the DIERS work that companies are interested in avoiding the release of chemicals to the environment in addition to preventing equipment damage. This adds considerable complexity to the relief system and must be evaluated with the same thoroughness as the vent design.     

A wavelet analysis for exploring the relationship between economic policy uncertainty and tourist footfalls in the USA

We attempt to establish the relationship between Economic Policy Uncertainty (EPU) and international tourist footfalls in the USA. In the first stage, we investigate the influence of country-specific EPU and global EPU on tourist footfalls. Since, these two are overlapping in nature, in the second stage, we study the isolated influence of country-specific EPU on footfalls by eliminating the influence of global EPU and vice versa. We consider a study period spanning over January 1997 to April 2017. To capture the variations in the relationship at different time dimensions, we apply wavelet-based techniques. We observe the following: (a) the impact of policy uncertainty shock has a little immediate impact on tourist footfalls, (b) medium to long-run shocks persist due to occurrence of major undesirable economic events, and (c) the influence of domestic (country-specific) EPU is dominant in comparison to global EPU for the USA.     

Management of Overseas Acquisitions by Developing Country Multinationals and Its Performance Implications: The Indian Example

Developing‐country multinationals (DMNCs) make overseas acquisitions to leverage extant capabilities of acquired companies in order to enter foreign markets and acquire their know‐how to enhance their own competitiveness against global competition at home and abroad. We go “inside the black box” to examine how DMNCs manage those acquisitions and the attendant implications for postacquisition performance. When DMNCs keep the acquired firm “structurally separate” from their own organization and retain its senior executives, they exhibit better acquisition performance. Also, “linking mechanisms” to coordinate interdependencies between the two firms improves performance, especially when the acquired firm is kept structurally separate. Analyses of large‐sample data of Indian DMNCs’ overseas acquisitions show that DMNCs’ light‐handed approach to managing acquisitions, despite acquiring majority ownership in them, seems suited to their acquisition objectives. © 2016 Wiley Periodicals, Inc.     

Stock splits, trading continuity, and the cost of equity capital

We hypothesize that managers use stock splits to attract more uninformed trading so that market makers can provide liquidity services at lower costs, thereby increasing investors’ trading propensity and improving liquidity. We examine a large sample of stock splits and find that, consistent with our hypothesis, the incidence of no trading decreases and liquidity risk is lower following splits, implying a decline in latent trading costs and a reduced cost of equity capital. Further, split announcement returns are correlated with the improvements in both liquidity levels and liquidity risk. Our analysis suggests nontrivial economic benefits from liquidity improvements, with less liquid firms benefiting more from stock splits.     

Getting offshoring right

The prospect of offshoring and outsourcing business processes has captured the imagination of CEOs everywhere. In the past five years, a rising number of companies in North America and Europe have experimented with this strategy, hoping to reduce costs and gain strategic advantage. But many businesses have had mixed results. According to several studies, half the organizations that have shifted processes offshore have failed to generate the expected financial benefits. What's more, many of them have faced employee resistance and consumer dissatisfaction. Clearly, companies have to rethink how they formulate their offshoring strategies. A three-part methodology can help. First, companies need to prioritize their processes, ranking each based on two criteria: the value it creates for customers and the degree to which the company can capture some of that value. Companies will want to keep their core (highest-priority) processes in-house and consider outsourcing their commodity (low-priority) processes; critical (moderate-priority) processes are up for debate and must be considered carefully. Second, businesses should analyze all the risks that accompany offshoring and look systematically at their critical and commodity processes in terms of operational risk (the risk that processes won't operate smoothly after being offshored) and structural risk (the risk that relationships with service providers may not work as expected). Finally, companies should determine possible locations for their offshore efforts, as well as the organizational forms--such as captive centers and joint ventures--that those efforts might take. They can do so by examining each process's operational and structural risks side by side. This article outlines the tools that will help companies choose the right processes to offshore. It also describes a new organizational structure called the extended organization, in which companies specify the quality of services they want and work alongside providers to get that quality.     

A dynamic multi-commodity model of the agricultural sector: A regional application in Brazil

This paper develops a dynamic model to analyze the development process in the agricultural sector. Formulated as a recursive linear programming model, it contains several commodities as outputs, farm and regional resource constraints on owned and purchased inputs-including working capital-and several farm sizes. The objective function is assumed to be separable for each farm size and additive for the region and measures for each year the net expected revenues from crop and livestock production less an investment charge. Prices are exogenous. The model is applied to a rapidly developing agricultural region in Southern Brazil and tested for its ability to trace regional farm sector development over a decade. It is then used to analyze the impact of alternative agricultural policies including price and credit subsidies.
