The geography of market failure: Edge-effect externalities and the location and production patterns of organic farming

Perceptions of increasing land scarcity and negative impacts of chemical-based agriculture have led to increasing concern regarding the sustainability of food systems. Incompatible production processes among farming systems may lead to spatial conflicts and production losses between neighboring farms, and the magnitude of such losses may depend not only on the scale of each activity, but also on patterns of land use. Such conflicts can be classified as “edge-effect externalities”—spatial externalities whose marginal impacts decrease as distance from the border generating the negative impact increases. This paper tests the hypothesis that edge-effect externalities have influenced the location and production patterns of certified organic farms, using data from California Central Valley certified organic farmers. Using concepts from landscape ecology and spatial statistics, we investigate difference in parcel geometry and surrounding land uses between organic and non-organic parcels. Using a generalized method of moments (GMM) spatially autoregressive econometric model, we demonstrate that both parcel geometry and surrounding land uses influence the probability of a given parcel being certified organic. We conclude with suggestions for policies to encourage development of organic farming regions.     

Cultural differences and judgment in financial reporting standards

This instructional resource provides you with the opportunity to explore how cultural differences can impact financial reporting outcomes through the judgments accountants make when interpreting and applying accounting standards. It is intended to draw your attention and awareness to culture’s impact on financial reporting judgments since financial reporting is becoming increasingly international in scope. The instructional resource begins by discussing financial reporting standards and cultural differences and then moves into presenting three accounting scenarios. The three scenarios (lease classification, contingent liability, and revenue recognition) examine how applying accounting standards requires judgment and how cultural differences can influence accountants’ judgments and the resulting financial reporting outcomes. In each scenario, you have the opportunity to identify and consider how different cultural dimensions could impact cross-cultural financial reporting outcomes. The instructional resource content allows you to consider the challenges in using and applying a uniform set of global accounting standards that require judgment across cultures.     

TRADE SIZES AND THEORIES OF THE BID-ASK SPREAD

Relations between trade-size characteristics and the bid-ask spread are developed to distinguish among major theories of the spread. These trade-size characteristics are determinants of the spread for NASDAQ/NMS stocks. They explain much of the cross-sectional variation in the spread commonly associated with volume, volatility, and share price. Evidence shows that order-processing costs are dominant relative to inventory effects for low-price, small-capitalization, and low-volume stocks, but that the opposite is true for high-price, large-capitalization, and high-volume stocks. Inventory effects are more important relative to asymmetric information costs when stock price or capitalization is lower.
