Tax efficiency in selected Indian states

This paper attempts to measure pure tax efficiency of fifteen major Indian states (Andhra Pradesh, Assam, Bihar, Haryana, Gujarat, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Orissa, Punjab, Rajasthan, Tamilnadu, Uttar Pradesh and West Bengal) for the period 1980–81 to 1992–93 in a manner that allows this efficiency to vary both across time as well as across states. It is discovered that there is a moral hazard problem in the design of central grants in that higher grants by the central government to the state governments reduce efficiency of tax collection by these states. The less poor states are more efficient in tax collection. The rankings of states by tax efficiency for the various years do not converge. An index of aggregate tax efficiency is calculated and it appears that this index has been stagnating. It is argued that the weight placed on tax effort in the formula determining central grants to state governments should be increased to improve tax efficiency of state governments.

Two-level search design for main-effect plus two plan

One important class of screening designs is the search design first proposed by Srivastava (1975). A new class of two-level factorial search designs which are capable of estimating all main-effect plus two interactions is provided. We first give a necessary and sufficient condition for the main-effect plus two plan and then show that the proposed search design always satisfies such a condition. Received October 2000     

The travel behaviour intentions of young people in the context of climate change

This article examines the factors influencing the future travel behaviour intentions of young people (aged 11–18), with specific attention given to how climate change considerations affect these. Overall it is found that the participants’ travel behaviour intentions are dominated by a desire to drive and that their values relating to identity, self-image, and social recognition (at the expense of their environmental values), as well as their affective attitudes towards transport modes, are key influences on this. Although they are aware of climate change, the participants’ understanding of the link between transport and climate change was weak. At the same time, they illustrated an apathy towards climate change – in part due to the timing and intangibility of its associated impacts and their lack of self-efficacy with respect to tackling this issue. However, despite claiming that their current environmentally friendly travel behaviours (such as walking or cycling to school) are not influenced by the issue of climate change, a number are accepting of the idea of enforced travel behaviour change – away from use of the car, towards more ‘environmentally friendly’ modes. This acceptance was in part due to their belief that such action would remove the influence of the ‘social dilemma’, where their own efforts to tackle climate change may be rendered worthless by the inaction of others.     

The effect of mixed versus blocked sequencing of promotion and prevention features on brand evaluation: The moderating role of regulatory focus

We investigate if presenting a brand's promotion and prevention features in homogenous blocks (e.g., two promotion features followed by two prevention features — a toothpaste that freshens breath, whitens teeth, stops plaque buildup and prevents cavities) as opposed to alternating their presentation order (a toothpaste that freshens breath, stops plaque buildup, whitens teeth, and prevents cavities) affects brand attitude. We find that alternating feature presentation improves brand evaluation among promotion-focused, but not prevention-focused, consumers. In mixed presentations, since each feature physically contrasts with those near it (e.g., promotion features bracketing a prevention feature), the resulting heightened distinctiveness increases the perceived variety of a brand's benefits and fits better with the advancement goals of promotion-focused consumers. We report two studies that support our predictions.     

Fast and frequent: Investigating box office revenues of motion picture sequels

This paper conceptualizes film sequels as brand extensions of a hedonic product and tests (1) how their box office revenues compare to that of their parent films, and (2) if the time interval between the sequel and the parent, and the number of intervening sequels, affect the revenues earned by the sequels at the box office. Using a random sample of 167 films released between 1991 and 1993, we find that sequels do not match the box office revenues of the parent films. However, they do better than their contemporaneous non-sequels, more so when they are released sooner (rather than later) after their parents, and when more (rather than fewer) intervening sequels come before them. Like other extensions of hedonic products, sequels exhibit satiation to the extent that their weekly box office collections fall faster over time relative to contemporaneous non-sequels. Managerial implications of the results are discussed.     

Variable split awards in a single-stage procurement model

We show that splitting an award can result in lower expected procurement costs, even in a one-time procurement setting, as long as entering the bidding competition is costly. For sufficiently risk-averse bidders, the split award mechanism provides additional insurance against the possiblity of losing the bid and, therefore, any bidding costs. This result contrasts with previous theoretical works which focus on one-time procurement and have concluded that multiple sourcing increases expected procurement costs.     

Book Review

This paper discusses partial approaches to trade liberalization, such as the Asia Pacific Economic Cooperation (APEC) group's Early Voluntary Sector Liberalization (EVSL) proposal and the "zero-for-zero" approach. Distortions to resource allocation and global markets that might result from partial liberalizations are discussed, and parallels drawn to the possible trade diversion impacts and welfare losses of regional liberalization and tariff escalation. A global Computable General Equilibrium (CGE) model is used to provide some numerical illustrations of the issues with respect to international trade in grains, oilseeds, and related processed products.     

Drivers of Shareholder Returns in Tech Industries (or How to Make Sense of Amazon's Market Value)

Earnings according to GAAP do a notoriously poor job of explaining the current values of the most successful high‐tech companies, which in recent years have experienced remarkable growth in revenues and market capitalizations. But if GAAP earnings fail to account for the values of such companies, are there other measures that do better? The authors address this question in two main ways. They begin by summarizing the findings of their recent study of both the operating and the stock‐market performance of 169 publicly traded tech companies (with market caps of at least $1 billion). The aim of the study was to identify which of the many indicators of corporate operating performance—including growth in revenues, EBITDA margins, and returns on equity—have had the strongest correlation with shareholder returns over a relatively long period of time. The study's main conclusion is that investors appear to be looking for signs of neither growth nor efficiency in using capital alone, but for an optimal mix or balancing of those goals. And that mix, as the study also suggests, is captured in a cash‐flow‐based variant of “residual income” the authors call “residual cash earnings,” or RCE. In the second part of their article, the authors show how and why RCE does a much better job than reported net income or EPS of explaining the current market value of Amazon.com , one of the best‐performing tech companies in the world. Mainly by treating R&D spending as an investment of capital rather than an expense, RCE reveals the value of a company that is distinguished by both the amount and the productivity of its ongoing investment—both of which have been obscured by GAAP.     

CREDIBILITY AND STRATEGIC LEARNING IN NETWORKS

We analyze a model of diffusion in a fixed, finite connected network. There is an interested party that knows the quality of the product being propagated and chooses an implant in the network to influence other agents to buy. Agents are either “innovators,” who adopt immediately, or rational. Rational consumers buy if buying instead of waiting maximizes expected utility. We consider the conditions on the network under which optimal diffusion of the good product with probability 1 is a perfect Bayes equilibrium.
