Child hunger in the developing world: An analysis of environmental and social correlates

Using two complementary methods in a framework that allows incorporating both environmental and household-level factors, we explore the correlates of underweight status among children. We use individual children as the units of analysis in 19 African countries, and subnational survey strata in 43 African, Asian and Latin American countries. We consider the relationship between household-level demographic and health survey data, environmental factors from external geospatial data sets and two indicators of malnutrition among children aged 1–3, deviations from the international standards of weight-for-age and height-for-age. We discuss methods for data integration. In general, household determinants explain more variation than environmental factors, perhaps partly due to more error-prone measurement at the community level. Among individual children, some measures of agricultural capacity are related to lower incidence of child hunger, while among regions, measures relating to urbanness and population density show a stronger relationship. We give recommendations for further study, data collection and policy making.     

Testing Q theory with financing frictions

We develop a Q theory of investment under financing constraints. The firm invests and saves optimally facing convex costs of external equity, overhang from outstanding debt, and collateral constraints on new borrowing. Overhang and costs of external equity discourage investment. Conversely, firms anticipating collateral constraints experience a side benefit from investing as installed capital relaxes future constraints. Empirical tests support the model. Conditional on average Q, investment is lower for equity issuers and for firms with large debt overhang. The Kaplan and Zingales and the Whited and Wu indices are used as proxies for future collateral constraints. Consistent with the model, both indices enter investment regressions positively.     

ESTIMATES OF THE AGGREGATE QUARTERLY CAPITAL STOCK FOR THE POST-WAR U.S. ECONOMY

We construct quarterly aggregate gross and net capital stock series for the post-war U.S. economy using annual capital stock, capital depreciation, and capital discard figures along with quarterly investment series. We construct nominal and real measures of all three categories in the aggregate capital stock: consumer durable goods, producer durable goods, and business structures. In constructing the nominal series we take into account the changes in capital goods' prices. The series are constructed using four different methods. Using time- and frequency-domain techniques, we compare the constructed series and characterize their short-run, business cycle, and long-run cyclical properties. We find that the constructed series exhibit very different cyclical and shock persistence dynamics. Practial implications are discussed.     

Emerging trends in retail pricing practice: implications for research

This article represents the first of several editorials to appear in the Journal of Retailing designed to examine the nexus between retail practice and research, with the goal of stimulating further research. This essay on emerging trends in pricing discusses recent advances in retail pricing optimization. We begin with a review of how retailers typically make pricing decisions using time-honored heuristics and attempt to infer the optimal decisions. However, current methods are suboptimal because they do not consider the affects of advertising, competition, substitute products, or complementary products on sales. Most fail to take into account how price elasticity changes over time, particularly for fashion merchandise, or how market segments react differentially to price changes. In addition, many retailers find it difficult to know how to price merchandise when their suppliers offer temporary “deals.” They are also generally unaware of how their pricing strategy influences their overall image. As these issues demonstrate, optimal pricing is not a static problem. Retailers must be able to react quickly to changes in the environment or sales patterns. This paper also provides examples of the more sophisticated pricing techniques that are currently being tested in practice. Finally, we conclude with a discussion of the critical components that must be incorporated into retail pricing.     

How does the theory of consumption values contribute to place identity and sustainable consumption?

The importance of consumers’ role in sustainable consumption is reflected in the vision of the Sustainable Development Education Panel: To educate consumers to make informed consumption decisions, to take responsibility for their actions and to realize the impact of consumption decisions on future generations. However, educating and informing consumers alone is unlikely to change deeply entrenched unsustainable consumption behaviour. A multi‐faceted approach is required – enforcing sustainable development initiatives through legislation, promoting corporate social responsibility programs on the part of business, and (most importantly), supporting communities that engage in sustainable consumption. This study examines the proposition that individuals who identify with their community (i.e. the residential suburb or a locality where identity is understood geographically) are more likely to engage in sustainable consumption. Specifically, it examines how consumption value (i.e. the perceived value of living in a particular residential suburb) contributes to place identity and to environmental attitudes and sustainable consumption behaviour. Structural equation modelling is used to verify the conceptual model using data from a telephone survey of 561 residents from two inner city suburbs in Auckland, New Zealand. The results support the proposition that environmental attitude and sustainable consumption behaviour is enhanced by consumption values through place identity. Residents who enjoy living in their community, value a clean and healthy environment and believe their suburbs are unique tend to develop a stronger identity with their residential suburb, and are more positive towards sustainable consumption. The results have important implications for social marketers, property marketers and city councils who strive to encourage sustainable consumption among its citizens.     

Dynamic legislative decision making when interest groups control the agenda

We consider dynamic decision making in a legislature, in which in each period legislators vote between the status quo (previous period?s policy) and a new bill. However, the agenda formation process is captured by interest groups, that is, the new bill on the agenda is determined by an all-pay auction among these groups. We show that convergence to the median voter of the legislature arises if interest groups are patient enough but not necessarily otherwise. We characterize the bound on the speed of convergence in a family of stationary equilibria in which policy bounces between right-wing and left-wing policies. We also show that convergence may be faster if organized interest groups represent only one side of the policy space, e.g., when only business and not consumer interests are organized.
