Apparent Gains,Hidden Costs: Examining Adoption Drivers,Yield, and Profitability Outcomes of Rotavator Tillage in Wheat Systems in Nepal

The ‘high speed’ rotavator is used for shallow tillage to create a fine tilth and incorporate crop residues, often with a single tractor pass. Rotavator tillage has spread quickly in many parts of South Asia, despite short-term experimental trials suggesting deteriorating soil quality and crop yield penalties. Evidence of rotavator impacts on farmer fields across soil gradients and time is largely absent. From a farm household survey conducted among wheat farmers in Nepal, we estimate wheat yield and profitability outcomes for rotavator adopters and non-adopters using propensity score matching. We find that rotavator adoption leads to inferior outcomes, despite significant cost savings for land preparation (US$ 11–15 per hectare). With rotavator adoption, farmers lose about 284–309 kg of wheat grain and about US$ 93–101 of profits on average per hectare per season, and these penalties increase with longer-term use of the technology. Adoption of rotavator appears to be driven by the cost and time savings for land preparation. Against this backdrop, new policy and extension efforts are required that discourage rotavator use and favour more sustainable tillage technologies.     

A Comparative Analysis of Earnings Forecasts in Europe

This study examines the accuracy and bias of financial analysts' EPS forecasts in nine European countries during 1987 to 1995. There are significant differences between the countries which may be due to the differences in earnings behaviour, accounting practices, and the influence of securities markets. An optimistic bias is endemic in European forecasts, consistent with research from the US. Investors who incorporate earnings forecasts in their stock selection procedures may be able to improve returns by explicitly adjusting their models for observed regularities in earnings forecast errors. However, we have shown that these regularities differ in incidence and magnitude across the countries studied, and further research is needed to effectively model these differences.     

An Empirical Analysis of the Political Economy of Tariffs

We seek to analyze the determinants of senatorial response to "generic" trade bills that seek to impose restrictions on the lowering of tariffs. The analysis is based on the response of senators to the trade expansion acts of 1962 and 1974. In the recent past these have been the only bills that are "generic" in nature since they are not targeted at any particular industry. Within the same framework we also examine the issue of "legislator shirking", a term used to imply the response of senators based on pure personal ideology rather than the interests of the constituents. Regression results show the growing influence of state specific factors and the diminishing role of party and personal ideology on senatorial response. Interestingly, we find that despite the similar generic nature of the two bills examined, the influence of personal ideology on the response of senators varies across the two bills examined.     

ESTIMATING THE IMPACT OF MAJOR LEAGUE BASEBALL GAMES ON LOCAL AIR POLLUTION

Professional sporting events attract millions of fans to urban areas each year as they cheer on their favorite teams. While benefits, such as increased tax revenues and economic development, are often cited as reasons to host a professional sports franchise, the public and private costs receive much less attention. This paper uses air quality readings from the Environmental Protection Agency and Major League Baseball schedules to estimate the impact of Major League Baseball games on local air pollution. The results suggest that attendance at a Major League Baseball game has a statistically significant but negligible impact on local air pollution. (JEL Q53, R11)     

The determinants of recovery from the Black Saturday bushfire: demographic factors,behavioural characteristics and financial literacy

We investigate the contribution of demographic factors, behavioural characteristics and financial literacy to recovery from the financial losses inflicted by the Black Saturday bushfire. Behavioural characteristics (such as overconfidence, self-serving and loss aversion biases) in conjunction with bushfire survivors’ knowledge of financial indicators are used to determine recovery time. Data are collected through in-depth interviews with bushfire survivors, academics and experts in natural disasters. The results show that demographic, behavioural and financial literacy factors have the potential to enhance the recovery process.

The relationship between top trading cycles mechanism and top trading cycles and chains mechanism

In this paper, we show that there is a relationship between two important matching mechanisms: the Top Trading Cycles mechanism (TTC mechanism proposed by Abdulkadiroglu and Sonmez, 1999) and the Top Trading Cycles and Chains mechanism (TTCC mechanism proposed by Roth, Sonmez, and Unver, 2004). Our main result is that when a specific chain selection rule proposed by Roth et al. is used, these two mechanisms are equivalent. While the equivalence is relevant for one specific case of the TTCC mechanism, it is a particularly interesting case since it is the only version identified by Roth et al. to be both Pareto-efficient and strategy-proof.     

Accounting for postretirement benefits: early adopters of SFAS 106

A study of companies that adopted SFAS 106 early reveals the companies generally have not funded retiree health benefits. The timing of a firm's adoption of the accounting standard is affected by a number of variables specific to that firm.     

Implementing Market Access

This paper examines ex post subsidies as a means of enforcing market share targets. Subsidies set after firms make their strategic decisions are shown to create powerful incentives for firms to raise prices. These effects are stronger when targets, and hence subsidies, are specified on a firm-specific rather than industry-wide basis. This occurs because firms perceive themselves as subject to more competition (i.e., more elastic demand) in the latter case.
