Canadian dairy policy and the returns to federal dairy cattle research

The economic surplus approach is used to estimate the returns to federal investments in dairy cattle research in Canada. A national supply function is estimated using time series data. Lagged research expenditures are included as explanatory variables in the model, facilitating the calculation of ***marginal as well as average benefits from research. Simulation analysis is used to study the effects of product market distortions associated with Canadian dairy policy as well as of the marginal excess burden on the rates of return to research and on the distribution of research benefits. Returns were found to be high at the margin. Distortions in the product market had a small effect on the overall returns to dairy cattle research but had a large impact on the distribution of research benefits. Rate of return estimates were found to be indicative of underinvestment even when the marginal excess burden was taken into account.     

Does Extension Work? Impacts of a Program to Assist Limited-Resource Farmers in Virginia

In this article the economic impacts of Virginia State University's Small Farm Outreach, Training, and Technical Assistance Program are assessed. Impacts are measured in terms of program effect on incomes of limited-resource participant farmers compared with their net farm incomes had they not participated. The program appears to significantly increase net farm income, provided there is sufficient intensity of participation. A single visit by an agent had no significant effect on income, suggesting a rationale for deepening participation intensity before broadening it. Aggregate program benefits may approach $5 million per year (for a cost of a few hundred thousand dollars).     

Do People Value The Welfare Of Farm Animals?

Public concern over farm animal welfare has led to the banning of a number of intensive farming methods such as sow stalls, battery cages (by 2012) and veal crates, and the development of high welfare status products sold at a price premium. This indicates that consumers value farm animal welfare. In addition satisfaction can also be derived, by consumers and non‐consumers of animal products, from the knowledge that all animals are experiencing welfare‐enhancing husbandry practices. Consequently farm animal welfare can be considered a complex good, sought partly for private consumption and as a public good. However, improving the welfare of all farm animals through legislation incurs costs ‐ are these increased costs of food production justified? We use contingent valuation to determine the economic value of improving the welfare of farm animals and find that people are willing to pay extra on their weekly food bill to ensure that laying hens, broiler chickens dairy cows and pigs have improved welfare conditions. The benefits of improving animal welfare are shown to exceed the costs of implementing these schemes. We conclude that improving the standards of legislation for farm animal welfare so that all farm animals experience higher standards of welfare can be economically justified.     

Model selection, estimation and forecasting in VAR models with short-run and long-run restrictions

We study the joint determination of the lag length, the dimension of the cointegrating space and the rank of the matrix of short-run parameters of a vector autoregressive (VAR) model using model selection criteria. We suggest a new two-step model selection procedure which is a hybrid of traditional criteria and criteria with data-dependant penalties and we prove its consistency. A Monte Carlo study explores the finite sample performance of this procedure and evaluates the forecasting accuracy of models selected by this procedure. Two empirical applications confirm the usefulness of the model selection procedure proposed here for forecasting.     

The value of feedback in forecasting competitions

In this paper we challenge the traditional design used for forecasting competitions. We implement an online competition with a public leaderboard that provides instant feedback to competitors who are allowed to revise and resubmit forecasts. The results show that feedback significantly improves forecasting accuracy.     

Product line pricing in a vertically differentiated oligopoly

Abstract This paper examines the joint pricing decision of products in a firm’s product line. When products are distinguished by a vertical characteristic, those with higher values of that characteristic will command higher prices. We investigate whether, holding the value of the characteristic constant, there is an additional price premium for products on the industry and/or the firm frontier, that is, for the products with the highest value of the characteristic in the market or in a firm’s product line. We also investigate the existence of price premia for lower‐ranked products and other product line pricing questions. Using personal computer price data, we show that prices decline with the distance from the industry and firm frontiers, even after holding absolute quality constant. We find evidence that consumer tastes for brands is stronger for the consumers of frontier products (and thus competition between firms weaker in the top end of the market). There is also evidence that a product’s price is higher if a firm offers products with the immediately faster and immediately slower computer chip (holding the total number of a firm’s offerings constant), possibly as an attempt to reduce cannibalization. Finally, a product’s price declines with the time it is offered by a firm, suggesting intertemporal price discrimination.     

Absorptive capacity, innovation, and financial performance

This study here examines the role of absorptive capacity as both a mechanism to identify and translate external knowledge inflows into tangible benefits, as well as a means of achieving superior innovation and time-lagged financial performance. Using path analysis in a sample of 461 Greek enterprises participating in the third Community Innovation Survey, this study demonstrates that external knowledge inflows are directly related to absorptive capacity and indirectly related to innovation. Absorptive capacity contributes, directly and indirectly, to innovation and financial performance but in different time spans. This study, therefore, contributes to the understanding of absorptive capacity's antecedents and outcomes by providing empirical evidence of longitudinal form that offers important research and practical implications.     

Does Female Directorship on Independent Audit Committees Constrain Earnings Management?

This study examines whether the gender of the directors on fully independent audit committees affects the ability of the committees in constraining earnings management and thus their effectiveness in overseeing the financial reporting process. Using a sample of 525 firm-year observations over the period 2003 to 2005, we are unable to identify an association between the proportion of female directors on audit committees and the extent of earnings management.     

Market Interest in Nonfinancial Information

During the past two decades, more and more companies have volunteered to provide “corporate social responsibility” or “sustainability” reports that include information about their environmental, social, and governance (ESG) policies and performance. Such reporting has come about largely in response to demands by a wide range of stakeholders for information about how the company's operations are affecting society in a number of different ways. But do investors really care about companies' ESG performance and policies? Using data from Bloomberg, the authors provide the first broadly based empirical evidence of investors' interest in ESG data. More specifically, the authors show how interest in the top 20 ESG metrics varies with geographical location (European vs. American), asset class (fixed income vs. equity), and firm type. At the aggregate market level, there is greater interest in environmental and governance information than in “social” information. U.S. investors are more interested than their European counterparts in governance and less interested in environmental information. Equity investors are interested in a wider range of nonfinancial information than are fixed income investors. And whereas sell‐side analysts are primarily interested in greenhouse gas emissions, money managers tend to focus on a broader set of metrics. Similarly, pension funds and hedge funds have shown interest in more nonfinancial metrics than insurance companies. The authors' bottom line: Companies need to recognize the growing market interest in nonfinancial information and ensure that they are providing it according to the specific information needs of market users.
