Electoral goals and center-state transfers: A theoretical model and empirical evidence from India

We construct a model of redistributive politics where the central government is opportunistic and uses its discretion to make transfers to state governments on the basis of political considerations. These considerations are the alignment between the incumbent parties at the central and state levels and whether a state is a swing state or not. A testable prediction from the model is that a state that is both swing and aligned with the central government is especially likely to receive higher transfers. We test this prediction using Indian data for 14 states from 1974–75 to 1996–97. We find that a state which is both aligned and swing in the last state election is estimated to receive 16% higher transfers than a state which is unaligned and non-swing.     

The effects of a “no-haggle” channel on marketing strategies

As sellers increasingly turn to multi-channel retailing, the opportunity to implement different pricing policies has grown. With the advent of the internet, many traditionally bargained products such as automobiles, jewelry, watches, appliances and furniture are now being offered online at a fixed pre-determined price. We explore the strategy of simultaneously offering two pricing formats (fixed and bargained) via two different channels (online and brick and mortar) and find that in a market where there are two types of consumers—those with a high cost of haggling and others with a lower cost—a dual-pricing strategy is optimal only when there are enough high haggling-cost consumers, but not too many, and when the haggling costs between the two types of consumers are sufficiently different. We also find that it is optimal for the seller to specify a higher-than-cost minimum acceptable price as the price floor of bargaining. By doing so, the seller increases the bargained price by complementing the salesperson's bargaining ability, and also softens the internal competition between the two channels. Finally, we find that, surprisingly, the dual-pricing strategy may serve fewer customers while still being more profitable than a single price structure. The implications for consumer surplus are also explored.     

Is Environmentally Friendly Agriculture Less Profitable for Farmers? Evidence on Integrated Pest Management in Bangladesh

Concerns about the sustainability of conventional agriculture have prompted widespread introduction of integrated pest management (IPM), an ecologically based approach to control harmful insects and weeds. IPM is intended to reduce ecological and health damage from chemical pesticides by using natural parasites and predators to control pest populations. Since chemical pesticides are expensive for poor farmers, IPM offers the prospect of lower production costs and higher profitability. However, adoption of IPM may reduce profitability if it also lowers overall productivity or induces more intensive use of other production factors. On the other hand, IPM may actually promote more productive farming by encouraging more skillful use of available resources. Data scarcity has hindered a full accounting of IPM's impact on profitability, health, and local ecosystems. Using new survey data, this paper attempts such an accounting for rice farmers in Bangladesh. We compare outcomes for farming with IPM and conventional techniques, using input-use accounting and conventional production functions. All of our results suggest that the productivity of IPM rice farming is not significantly different from conventional farming. Since IPM reduces pesticide costs with no countervailing loss in production, it appears to be more profitable than conventional rice farming. Our interview results also suggest substantial health and ecological benefits. However, externality problems make it difficult for farmers to adopt IPM individually. Without collective adoption, neighbors' continued reliance on chemicals to eliminate pests will also kill helpful parasites and predators, as well as expose IPM farmers and local ecosystems to chemical spillovers from adjoining fields. Successful IPM adoption may therefore depend on institutional support for collective action.     

Do Intra-Household Effects Generate the Food Stamp Cash-Out Puzzle?

Previous empirical studies have noted the higher marginal propensity to consume food out of food stamps in the United States, compared to that out of cash income. Analyzing data from U.S. Food Stamp Program participants, we find evidence that this discrepancy may be driven primarily by the behavior of multiple-adult households. Single-adult households show no evidence of any discrepancy. Thus, our results suggest that food stamp and cash income (welfare or market) may have very different impact on the intra-household allocation process, and that this is reflected empirically in the cash-out puzzle.     

Water pollution abatement by Chinese industry: cost estimates and policy implications

Factory-level data are used to estimate water pollution abatement costs for Chinese industry. Joint abatement cost functions are utilized which relate total costs to treatment volume and the simultaneous effect of reductions in suspended solids, chemical oxygen demand, biological oxygen demand and other pollutants. Tests of alternative functional forms suggest that a very simple (constant elasticity) model fits the data as well as a complex (translog) model, permitting sophisticated policy experiments with relatively simple calculations. From the results, the cost-effectiveness of current pollution control policy in China is analysed. Basic conclusions are (1) The benefits of stricter discharge standards should be weighed carefully against the costs. For the sample of 260 factories, a shift across the existing range of standards entails a present-value difference of US$330 million in abatement costs. (2) Emissions charges as low as US$1.00/ton would be sufficient to induce 80% abatement of suspended solids for cost-minimizing factories. Charges of US$3, US$15 and US$30 per ton would be sufficient to induce 90% abatement of TSS, COD and BOD. (3) The current regulatory system provides an economic incentive to abate by charging a levy on pollution in excess of the standard. However, the results suggest that changing to a full emissions charge system would greatly reduce overall abatement costs. For the 260 factories in the sample, the current overall abatement rate could be attained under a charge system at a reduced annual cost whose present value is US$344 million.     

Environmental Regulation and Development: A Cross-country Empirical Analysis

This paper develops comparative indices of environmental policy and performance for 31 countries, using a quantified analysis of reports prepared for the United Nations Conference on Environment and Development (UNCED). In cross-country regressions, we find a very strong, positive association between our indicators and the level of economic development, particularly when the latter is adjusted for purchasing power parity. Our results suggest a characteristic progression in the development process, from protection of natural resources to regulation of water pollution and, finally, air pollution control. They also highlight the importance of institutional development, with significant roles for degree of private property protection, effectiveness of the legal/judicial system and efficiency of public administration. Controlling for these variables, "Green" sector indices should be positively correlated with: (1) rural population density; and (2) agricultural and forest production share of national output. "Brown" sector indices should be positively correlated with: (1) particular focus on public health, indexed by life expectancy; (2) urban share of total population; (3) urban population density; and (4) manufacturing share of national output. Our analysis of overall regulatory performance reveals strong cross-country associations with income per capita, security of property rights, and general development of the legal and regulatory system. Surprisingly, however, we find only insignificant or perverse associations with degree of popular representation and freedom of information. For both the Green and Brown indices, performance is again strongly associated with income per capita, freedom of property and (in small samples) measures of regulatory efficiency. The two specifically rural sector variables (population density; proportion of GDP in agriculture and forestry) are only weakly associated with the Green index. The fit is much better for the Brown index: degree of urbanization, population density and manufacturing share in GDP all have the expected signs and relatively high significance. Life expectancy as a proxy for public health priority has no independent effect. In summary, our findings suggest that a detailed, quantified analysis of the UNCED reports can yield comparable and plausible indices of environmental policy performance across countries. Cross-country variations in our environmental index are explained well by variations in income per capita, degree of urbanization and industrialization, security of property rights and general administrative efficiency.     

Bargaining, Bonding, and Partial Ownership

This article provides a theory of interfirm partial ownership. We consider a setting in which an upstream firm can make two alternative types of investment: either specific investment that only a particular downstream firm can use or general investment that any downstream firm is capable of using. When the benefits from specific and general investments are both stochastic, equity participation by the downstream firm in the upstream firm can lead to more efficient outcomes than take-or-pay contracts. The optimal ownership stake of the downstream firm is less than 50 percent under a natural assumption about relative bargaining power.
