Strategic Decentralization and Channel Coordination

In this paper, we show that under certain conditions, strategic decentralization through the addition of a retailer in the distribution channel can increase a manufacturer's profits. The specific case on which we focus is the quantity coordination (double marginalization) problem for a manufacturer selling durable goods in a two-period setting. We show that the standard solution that coordinates a channel for non-durables does not coordinate the channel for durables. In particular, even though a manufacturer can achieve channel coordination by offering per-period, two-part fees, the equilibrium wholesale price in the first period is strictly above the manufacturer's marginal cost. This is in stark contrast to the two-part solution for non-durables where the equilibrium wholesale price is equal to marginal cost. We also identify a strategy that solves both the channel coordination and the Coase problem associated with durable goods. In this strategy, at the beginning of period 1, the manufacturer writes a contract with the retailer specifying a fixed fee and wholesale prices covering both periods. We show that by adding a retailer and using this contract, the manufacturer makes higher profits than it could if it were to sell directly to consumers.     

Do consumer perceptions matter in measuring choice variety and variety seeking?

This research marries scanner panel choice data of consumers in single member households to their survey-based perception data and draws upon behavioral and modeling research to contribute to the variety seeking literature. It presents a new consumer-based measure of choice variety based on inter-product similarity perceptions and illustrates that others-based (i.e., researchers, managers, and retailers) measures of choice variety such as number of brand switches underestimate choice variety. Moreover, incorporating the consumer-based measure instead of others-based measures in latent class models improves their efficiency of classifying households into high versus low variety seeking. The consumer-based measure of choice variety is valid in terms of its positive relationship with consumer's intrinsic or trait-based variety seeking tendency. Theoretical (market structure, consideration set) and managerial implications (targeting of price promotions to reduce spending, product design, cross-price elasticity) of the findings are offered.     

Divisional Informativeness Gap and Value Creation from Asset Sales

Nanda and Narayanan (1999) show that the information asymmetry between the managers and market participants regarding divisional cash flows helps explain the value creation on asset sales. Based on their theoretical framework, the divisional informativeness gap hypothesis predicts that the announcement‐period return increases with the difference in cash‐flow informativeness of retained and divested divisions prior to the divestiture. Our results, using industry‐average earnings response coefficient as a proxy for cash‐flow informativeness of a division, support this prediction. The effect is stronger when a conglomerate retains the division with relatively greater growth opportunities.     

The Impact of Transportation Infrastructure on Women's Employment in India

ABSTRACT

Indian women's labor force participation is extremely low, and women are much less likely than men to work in the nonfarm sector. Earlier research has explained women's labor supply by individual characteristics, social institutions, and cultural norms, but not enough attention has been paid to the labor market opportunity structure that constrains women's labor market activities. Using data from the India Human Development Survey (IHDS) in 2004–05 and 2011–12, this study examines how village transportation infrastructure affects women's and men's agricultural and nonagricultural employment. Results from fixed-effect analysis show that access by paved or unpaved roads and frequent bus services increase the odds of nonagricultural employment among men and women. The effect of road access on nonfarm employment (relative to not working) is stronger among women than among men. Improved transportation infrastructure has a stronger positive effect on women's nonfarm employment in communities with more egalitarian gender norms.     

Cost-minimization comparison of darunavir plus ritonavir and lopinavir/ritonavir in HIV-1 infected treatment-naïve women of childbearing age

Background:

Guidelines from the Department of Health and Human Services in the US recommend ritonavir-boosted lopinavir (LPV/r) as a preferred protease inhibitor (PI) for HIV-positive antiretroviral-na?ve pregnant women. These guidelines also cite ritonavir-boosted darunavir (DRV?+?RTV) as an alternative PI in this clinical scenario. The purpose of this analysis was to compare economic outcomes for regimens based on these two treatments.

Study design:

An existing discrete event simulation (DES) model was adapted to conduct a cost-minimization analysis comparing the two regimens in HIV-infected women of childbearing age (WOCBA), from the perspective of a healthcare payer in the US.

Methods:

The DES model was used to represent disease states, health events, healthcare encounters, pregnancy, and treatment choices in HIV-infected WOCBA starting treatment with regimens based on either LPV/r or DRV?+?RTV. It also incorporated parameters for individual patient characteristics, and for antiretroviral (ARV) treatment effectiveness, treatment sequencing, clinical progression, and resource use. Potential events included scheduled physician visits; viral suppression; viral rebound; AIDS-related complications; CHD events; treatment discontinuation and switching; ARV treatment side-effects (SE); and death. The primary outcomes were discounted 5-year and 10-year healthcare costs. Alternative scenarios considered different rates of switching from DRV?+?RTV to LPV/r upon conception.

Results:

Compared with DRV?+?RTV, LPV/r was associated with similar clinical outcomes while offering savings at the 5- and 10-year horizons (of $24,904 and $43,502 per patient, respectively), and in extensive sensitivity analyses. The main driver of the savings was the difference in cost between PIs.

Conclusions:

Starting HIV-infected ARV-treatment-na?ve WOCBA on an LPV/r-based regimen is cost-saving and provides similar patient outcomes compared to a DRV?+?RTV-based regimen.
