Monetary policy and the behaviour of inflation in India: Is there a need for institutional reform?

Inflation rates in a number of developed countries follow a common trend over the past five decades: inflation starts out low in the 1950s, rises for a time before peaking in the 1970s, and then falls back to initial levels. Interestingly the behaviour of trend inflation in India broadly exhibits such a pattern. This similarity in the behaviour suggests that any explanation of inflation ought to apply across countries. To this end we construct a reduced-form inflation model for India that encompasses various well-known policy mistake theories as special cases. The restriction imposed by each of these theories on the behaviour of inflation is tested empirically. Reduced-form estimates lend support to all these theories. Although the reason for the inflation bias differs from one theory to the other, the mechanism at the heart of these theories are in fact quite similar. They all lay responsibility for inflation with the nature of monetary institutions. We use these results to interpret India's inflation experience over the past five decades and discuss the implications for institutional reform.     

PERHAPS EVA DOES BEAT EARNINGS—REVISITING PREVIOUS EVIDENCE

In two articles, the first published in 1997 in the Journal of Accounting and Economics and the second in 1999 in this journal, Gary Biddle, Robert Bowen, and James Wallace presented evidence that reported earnings are more closely related than EVA to marketadjusted stock returns– in other words, that earnings are more “value relevant” than EVA. These papers, which are among the most widely cited in finance and accounting, fundamentally affected perceptions about the importance of EVA as a measure of corporate performance. The current article addresses a simple question: Do the Biddle, Bowen, and Wallace results continue to hold for a different set of companies, a different time period, and a different market? The authors first examined updated EVA information for different companies in the same time period examined in the Biddle, Bowen, and Wallace study. They then looked at a more recent time period (1995–1999) and a different market (the Canadian stock market), and found in all cases that “EVA has greater power than earnings in explaining marketadjusted stock returns.” Their findings validate the widespread corporate acceptance of EVA as a management tool.     

HEDGED DIVIDEND CAPTURE AND EX-DAY RETURNS: AN EMPIRICAL UPDATE

We find that the magnitude of abnormal ex-day returns exhibited by US equities diminished in 1987 and 1988, subsequent to the US Tax Reform Act of 1986. We also report the results of a dividend capture strategy, hedged with the sale of stock index futures contracts. Hedging removes more than 50 percent of the risk of dividend capture, and even after transactions costs, can provide returns in excess of buying and holding the market portfolio of equities.     

Procurement bidding with restrictions

In many procurement situations with simultaneously offered projects, firms face participation restrictions and can bid only on a subset of the projects. This phenomenon is prevalent in a variety of observed situations such as bidding for private label supplies, business to business procurement or government projects. We show that for the case of n bidding firms where each is restricted to bid on a subset of the offered projects, there exists a symmetric equilibrium in which each bidder has a positive expected equilibrium profit. Prices are bounded away from marginal costs even if all the bidders are homogenous. This results from the fact that there is a positive probability that each firm will find itself in the position of being the sole bidder on a project. While the equilibrium probability of bidding on a project increases with its value, it is interesting to note that the bidding probability on the projects approaches an equiprobable one as the number of bidding firms increases. We find that the equilibrium profits decrease as firms are able to bid on more of the available projects. In contrast, bidder commitment to bid on specific projects increases the equilibrium profits of all firms. We also examine the effect of heterogeneity on equilibrium profits. Greater heterogeneity in the project valuations leads to lower firm profits. On the other hand, heterogeneity among bidders in terms of the number of projects that they are constrained to bid on leads to greater profits for the firms that can bid on more projects (regardless of the mix of the firms in the industry.) Finally, we analyze the effect of uncertainty in project valuations and show greater uncertainty in project valuations (as represented by a mean preserving spread) decreases the equilibrium profits. We conclude with an empirical analysis of bidding behavior that tests the predictions of the theory. We find that the probability of bidding on a particular project is increasing in its value, decreasing in the other projects values and decreasing in the number of bidding subjects. Furthermore, the value of the bids on a project increase with its valuation and decrease with the total number of bidders.

Quantity Discounts, Manufacturer and Channel Profit Maximization: Impact of Retailer Heterogeneity

In this paper, we investigate if a manufacturer can simultaneously maximize own and channel profit with any quantity-based pricing policy, including a quantity-discount policy, when selling through heterogeneous retailers. We show that the manufacturer's best possible pricing policy, when retailers self-select quantities, is a quantity discount. However, this policy does not maximize channel profit. Driven by the manufacturer's inclination to reduce the quantity sold through a high-cost or low-demand retailer, this result holds whether or not retailers compete. We discuss implications of our analysis for the manufacturer.     

Land change in the Brazilian Savanna (Cerrado), 1986–2002: Comparative analysis and implications for land-use policy

The Brazilian Cerrado, a biodiverse savanna ecoregion covering 1.8 million km² south and east of the Amazon rainforest, is in rapid decline because of the expansion of modern agriculture. Previous studies of Cerrado land-use and land-cover (LULC) change imply spatial homogeneity, report widely varying rates of land conversion, use ambiguous LULC categories, and generally do not attempt to validate results. This study addresses this gap in the literature by analyzing moderate-resolution, multi-spectral satellite remote sensing data from 1986 to 2002 in two regions with identical underlying drivers. Unsupervised classification by the ISODATA algorithm indicates that Cerrado was converted to agro-pastoral land covers in 31% (3646 km²) of the study region in western Bahia and 24% (3011 km²) of the eastern Mato Grosso study region, while nearly 40% (4688 km² and 5217 km², respectively) of each study region remained unchanged. Although aggregate land change is similar, large and contiguous fragments persist in western Bahia, while smaller fragments remain in eastern Mato Grosso. These findings are considered in the current context of Cerrado land-use policy, which is dominated by the conservation set-aside and command-control policy models. The spatial characteristics of Cerrado remnants create considerable obstacles to implement the models; an alternative approach, informed by countryside biogeography, may encourage collaboration between state officials and farmer-landowners toward conservation land-use policies.
