Catastrophic crop insurance effectiveness: does it make a difference how yield losses are conditioned? AgEcon
Bokusheva, Raushan; Conradt, Sarah.
The study evaluates the effectiveness of a catastrophic drought-index insurance developed by applying two alternative methods - the standard regression analysis and the copula approach. Most empirical analyses obtain estimates of the dependence of crop yields on weather by employing linear regression. By doing so, they assume that the sensitivity of yields to weather remains constant over the whole distribution of the weather variable and can be captured by the effect of the weather index on the yield conditional mean. In our study we evaluate, whether the prediction of farm yield losses can be done more accurately by conditioning yields on extreme realisations of a weather index. Therefore, we model the dependence structure between yields and weather by...

Limitations of Granger Causality Analysis to assess the price effects from the financialization of agricultural commodity markets under bounded rationality AgEcon
Grosche, Stephanie.
Modern agricultural commodity markets are simultaneously governed by a physical and a financial market element. Whether financial “index trading” activity influences price levels on the futures markets has been investigated by empirical studies using Granger Causality Analysis. A critical review of these studies reveals inconclusive results. Based on sensitivities of the method, reasons for limited interpretability of results may be omitted determinants of financial trading activity, failure to consider the informational efficiency of markets, time-varying and feedback effects of boundedly rational heterogeneous trading strategies and limitations in specifying adequate theoretical variables from existing data.

Methodische Ansätze zur Quantifizierung der Arbeitsplatzeffekte von Maßnahmen zur ländlichen Entwicklung AgEcon
Margarian, Anne.
Zusammenfassung: In der vorliegenden Arbeit werden mögliche methodische Ansätze zur Beurteilung von Arbeitsplatzeffekten von Fördermaßnahmen für den ländlichen Raum und insbesondere der Integrierten Ländlichen Entwicklung (ILE) vorgestellt und diskutiert. Aufgenommen wurden auch Methoden, deren Eignung für diese spezifischen Bewertungen verneint wird. Aus diesem Grund ist die vorliegende Arbeit nicht nur mit Blick auf die Bewertung der ILE zu lesen, sondern kann auch über mögliche Herangehensweisen an die Bewertung anderer Maßnahmen zur Entwicklung des ländlichen Raumes informieren. Die Diskussion der verschiedenen Methoden zeigt, dass es notwendig ist, die einer Wirkung zugrunde liegenden Zusammenhänge genau zu kennen, um die tatsächliche Wirkung einer...

Methodological and practical solutions for the evaluation of the economic impact of RDP in Latvia AgEcon
Veveris, Armands.
The paper analyses methodological and practical solutions that have been introduced to assess the impact of the Rural Development Programme 2007-2013 in Latvia. The work on the development of the evaluation of the impact of rural support is only in progress, the range of data sources is not large either. Therefore the author offers a solution how the evaluation of the RDP is organized in Latvia, with the resources and the amount of information available, and what activities are planned in the future. Special attention is devoted to the development of the methodology for calculating the direct economic effect, including the principles of the formation of the group of the affected farms and the control group, as well as the choice of the range of indicators...

Modeling Advertising Expenditures and Spillover Effects Applied to the U.S. Non-Alcoholic Beverage Industry: Vector Autoregression (VAR) and Polynomial Distributed Lag (PDL) Approaches AgEcon
Dharmasena, Senarath; Capps, Oral, Jr.; Bessler, David A..
The non-alcoholic beverage market in the U.S. is a multi-billion dollar industry growing steadily over the past decade. Also, non-alcoholic beverages are among the most heavily advertised food and beverage groups in the United States. Several studies pertaining to non-alcoholic beverages including the incorporation of advertising effects have been conducted, but most of these have centered attention on milk consumption. Some studies have considered demand interrelationships for several beverages including advertising effects in systems-wide analyses. In our analysis, we develop and employ a unique monthly time-series data set derived from Nielsen Homsescan panels for household purchases of non-alcoholic beverages over the period from January 1998 through...

Polarized Preferences In Homegrown Value Auctions AgEcon
Hurley, Terrance M.; Yue, Chengyan; Anderson, Neil O..
Incentive compatible auction experiments, often referred to as homegrown value auctions, have become a popular tool for exploring how controversial product attributes and knowledge of these attributes affect consumer willingness to pay. A common observation in these experiments is a prevalence of zero bids and bimodal bid distributions. One possible explanation is that individuals have polarized preferences: find all products with a particular attribute desirable (positive polarization) or undesirable (negative polarization). The purpose of this paper is to explore three questions. Do polarized preferences exist? If they do exist, can they be identified? If they can be identified, does their identification provide useful information? To answer these...
