Private Label Vendor Selection in a Supply Chain: Quality and Clientele Effects

We model a supply chain consisting of a national brand manufacturer and an independent manufacturer, both of whom are potential suppliers of store brand to a single retailer. The retailer serves two customer segments—a quality sensitive segment (high type) and a price sensitive (low type) segment. The retailer serves these two segments by targeting the national and store brands to the quality and price sensitive segments, respectively. When the national brand manufacturer supplies the store brand he internalizes the effect of store brand quality on the national brand's retail prices. This leads the national brand manufacturer to choose a lower store brand quality than the independent manufacturer. This decrease in store brand quality has the benefit of increased revenues from the high type customers along with an associated cost of decreased revenues from the low type customers. Thus, when the benefit outweighs the cost the retailer chooses the national brand manufacturer to supply the store brand. We show that the retailer will choose the national brand manufacturer to supply the store brand when (a) the size of the high type customer segment is large relative to the low type customer segment, (b) the valuations of the high type customer segment is large relative to the low type customer segment, and (c) the retailer's margin requirement on the store brand is not very high. Overall, these results suggest that retailers who serve a bigger sized quality (price) sensitive clientele would have the national brand (independent) manufacturer supply the store brand.     

A Structural VAR (SVAR) analysis of fiscal shocks on current accounts in India

The stimulus packages announced to deal with the economic slowdown has increased the fiscal deficit of many countries and it spurred the debate on the possible effect of these fiscal shocks on other economic variable especially the current account. In this study, we examine the effect of fiscal deficit on current account of India using the VAR as well as the Structural VAR (SVAR) analysis. Our analysis indicates that the fiscal deficit is positively affecting the current account deficit in India, as predicted by the twin deficit hypothesis. Therefore, the historical data indicates the presence of the twin deficits phenomenon in Indian context.     

Is Financial Flexibility a Priced Factor in the Stock Market?

This paper develops a factor analysis–based measure for shifts in corporate financial flexibility (FFLEX) that can be observed from public accounting information. Companies that experience positive shifts in FFLEX are associated with higher future investment growth opportunities. We show that FFLEX is a robust determinant of future stock returns. Firms that have increased their financial flexibility are associated with lower stock returns in the subsequent period. A zero‐cost return portfolio produces a significant positive monthly premium of 0.69%, which is driven by covariance (risk). Risk inherent in the flexibility factor is not explained away by either prominent pricing characteristics or factors.     

Transparency and incentives among peers

This article studies the effect of transparency among peers on the principal's cost of providing incentives. Using directed graphs to represent peer information, we show that under complementarity the cost of providing incentives is decreasing with the level of transparency within the organization. We also investigate the role of the architecture of the information in boosting incentives. In arguing that substitution impedes the benefits of transparency, we will compare function‐based teams with process‐based teams, showing that the latter are more effective in providing incentives.     

Large time and small noise asymptotic results for mean reverting diffusion processes with applications

Summary. We use the theory of large deviations to investigate the large time behavior and the small noise asymptotics of random economic processes whose evolutions are governed by mean-reverting stochastic differential equations with (i) constant and (ii) state dependent noise terms. We explicitly show that the probability is exponentially small that the time averages of these process will occupy regions distinct from their stable equilibrium position. We also demonstrate that as the noise parameter decreases, there is an exponential convergence to the stable position. Applications of large deviation techniques and public policy implications of our results for regulators are explored. Received: December 7, 1998; revised version: October 25, 1999     

Continuous-Time Methods in Finance: A Review and an Assessment

I survey and assess the development of continuous-time methods in finance during the last 30 years. The subperiod 1969 to 1980 saw a dizzying pace of development with seminal ideas in derivatives securities pricing, term structure theory, asset pricing, and optimal consumption and portfolio choices. During the period 1981 to 1999 the theory has been extended and modified to better explain empirical regularities in various subfields of finance. This latter subperiod has seen significant progress in econometric theory, computational and estimation methods to test and implement continuous-time models. Capital market frictions and bargaining issues are being increasingly incorporated in continuous-time theory.     

Combinatorial agency

We study a combinatorial variant of the classical principal-agent model. In our setting a principal wishes to incentivize a team of strategic agents to exert costly effort on his behalf. Agents? actions are hidden and the principal observes only the outcome of the team, which depends stochastically on the complex combinations of the efforts by the agents. The principal seeks the mechanism that maximizes the principal?s net revenue given an equilibrium behavior of the agents. We investigate the structure of the optimal mechanism for various production technologies as the principal?s value from the project varies. In doing so we quantify the gap between the first-best and second-best solutions. Our results highlight the qualitative and quantitative differences between production technologies that exhibit complementarities and substitutabilities between the agents? actions. In comparing the first best with the second best we highlight the role of effort monitoring by the principal. As we shall see, the benefit from monitoring crucially depends on the underlying technology, with the two polar cases being perfect substitution and perfect complementarity.     

DEVELOPMENTS IN PUBLIC SECTOR PERFORMANCE MEASUREMENT: A PROJECT ON PRODUCING RETURN ON INVESTMENT METRICS FOR LAW ENFORCEMENT

This paper reports on a project concerned with developing a return on investment (ROI) performance metric for a law enforcement organisation. The paper's contributions are twofold. First, it addresses concerns in the literature about how different stakeholder interests are balanced in the development of performance measures. Second, it helps to remedy an oversight in the literature regarding the hybridisation of accounting and economic expertise, whereby cost benefit techniques and ROI combine to produce a metric of public sector achievements. By virtue of its law enforcement context the paper also discusses a further hybridisation where accounting, economics and criminology/law enforcement intersect.
