Bundling agricultural technologies to adapt to climate change

Farmers can respond to climate change by modifying their technologies or management practices, or both. In this paper, we examine the choice of crop, irrigation, and cover as a bundled decision by a farmer. Using discrete choice analysis and a cross section of farms from Israel, we test whether these decisions are sensitive to climate and find that they are. In the case of Israel, the farmers completely substitute capital for climate. Simulating increase in temperature suggests that warming would lead Israeli farmers to shift mainly to orchards under cover and irrigation. But it is likely that bundling adaptations will provide flexibility and sustainability for future farmers in many locations under climate change conditions.     

How to Count Patents and Value Intellectual Property: The Uses of Patent Renewal and Application Data

Patent counts are very imperfect measures of innovative output. This paper discusses how additional data—the number of years a patent is renewed and the number of countries in which protection for the same invention is sought—can be used to improve on counts in studies that require a measure of the extent of innovation. Simple weighting schemes are proposed, which may remove half of the noise in patent counts as a measure of innovative output. We describe models of the patent application and renewal processes whose parameter estimates can be used to assess the value of the proprietary rights created by the patent laws. We illustrate their use with estimates of how the value of patent protection would vary under alternative legal rules and renewal fees and with estimates of the international flows of returns from the patent system. Recent progress in the development of databases has increased the potential for this type of analysis.     

ACCOUNTABILITY AND CORRUPTION: POLITICAL INSTITUTIONS MATTER

This study uses a cross-country panel to examine the determinants of corruption, paying particular attention to political institutions that increase accountability. Even though the theoretical literature has stressed the importance of political institutions in determining corruption, the empirical literature is relatively scarce. Our results confirm the role of political institutions in determining the prevalence of corruption. Democracies, parliamentary systems, political stability, and freedom of press are all associated with lower corruption. Additionally, common results of the previous empirical literature, related to openness and legal tradition, do not hold once political variables are taken into account.     

Welfare consequences of water supply alternatives in rural Tunisia

Many economic studies have addressed the issue of inefficiency of public water supply in rural areas and the potential for improved service by private companies. Many of these analyses focused on identifying either willingness to pay or comparing average service costs and prices paid by customers. This paper performs a welfare analysis of two water supply systems—public and self owned—in rural Tunisia. The paper calculates consumer and producer surplus and compares the performance of the two systems from a social point of view. Results suggest that both systems are inefficient, mainly because of a production level that is low compared with production capacity.     

The HIV/AIDS crisis and corporate moral responsibility in the light of the Levinasian notions of proximity and the Third

This paper focuses on the set of problems regarding the HIV/AIDS crisis in the specific domain of corporate moral responsibility within a context of the Levinasian notion of proximity (infinite responsibility) and the Third. Against a totalitarian, homogeneous society, Levinas opens the way to a social pluralism, which has its sources in the disquiet provoked by the strangeness of the Other's face. Corporate responsibility, understood from this point of view, would not reduce institutional relations to an anonymous world of neutrality. Corporate responsibility is unconditional in the sense that to be responsible is not a question of choice, but one of deep liberty, the liberty of taking the burden of the infinite responsibility for the Other – customers, employees, the public at large and those who suffer in the world. This paper argues that it would then also mean that society (individuals, NGOs and governments) in accordance with the spirit of the Levinasian philosophy of infinite responsibility could exert pressure on corporations, such as pharmaceutical companies. Owing to their power, they could change their present responsibility policies to a more affirmative and engaged responsibility with regard to those who are ill and who suffer death or debilitation from HIV/AIDS and other prevalent diseases in the poorest parts of the world today.     

The Relative Efficiency and Implementation Costs of Alternative Methods for Pricing Irrigation Water

A useful means for achieving efficient allocation of irrigationwater is to put the right price tag on it. This article discussessome of the more pervasive pricing methods and compares theirefficiency performance, paying special attention to the impactof the cost of implementing each method on its efficiency. Thearticle uses an empirical example to demonstrate numericallythe relative efficiency of the different pricing methods andthe important role of implementation costs. The volumetric,output, input, tiered, and two-part tariff methods all can achieveefficiency, although the type of efficiency varies from onemethod to another. These methods also differ in the amount andtype of information, and the administrative cost, needed intheir implementation. The example indicates that water pricingmethods are most pronounced through their effect on the croppingpattern—more so than through their effect on water demandfor a given crop. Implementation costs have a large effect onwater tariffs and on welfare and hence should have an importantrole in determining the desirable method to use in any givenwater situation.     

Response to advertising on online social networks: the role of social capital

The objective of this study is to analyse the marketing value obtained from developing and maintaining social relationships through online social networks (OSNs). We propose and test a structural model that considers a number of antecedents to response to advertising, namely social capital, social status and sociability. Data was gathered through the administration of a structured online questionnaire to a sample of 274 OSN users. Results show that social capital derived from participating in OSNs has a positive impact on social status and sociability; in turn this has a positive impact in response to advertising. This study advances theory by analysing the impact of bonding and bridging social capital on both social status and sociability. Additionally, it examines the impact of both of these constructs on response to advertising. The confirmation of the significance of social capital gained through participation in OSNs and its impact on response to ads provides support for the notion that the relationally oriented and marketing‐oriented management of OSNs are compatible. These findings are of great relevance for the appropriate management of company presence on OSNs.     

The Israeli XBRL Adoption Experience

eXtensible Business Reporting Language (XBRL) is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It is a tool to bridge potential language barriers and unify financial reporting. This has appeal to foreign investors, among others, who can rely on information in XBRL‐tagged financial reports to make investment decisions without having to translate financial statements from local language. In 2008, Israel required most public companies to adopt International Financial Reporting Standards (IFRS) for financial reporting and to use XBRL‐tagged reporting format, as part of an aggressive effort to make its capital markets more transparent and attractive for foreign investors. In this paper, we study all Israeli public companies and analyze the accuracy and reliability of their XBRL‐tagged financial statements that are available on MAGNA, the Israel Securities Authority's electronic system. We describe the process by which the XBRL‐based data were collected and reported. We document, categorize, and analyze deficiencies in the XBRL‐tagged filings, and inconsistencies between them and the Hebrew‐based annual reports. We observe pervasive data entry errors resulting in inaccurate XBRL‐generated financial reports, which went undetected for over one year. Further, first year XBRL reporting (in conjunction with IFRS adoption) did not increase foreign investment in the Israeli capital markets. This analysis allows us to better understand the benefits and challenges of the adoption of XBRL.     

ECONOMIC FREEDOM AND STATE BOND RATINGS

Are state bond ratings, ceteris paribus, related to economic freedom? We test for the relationship between economic freedom and an aggregate index comprised of ratings by Standard & Poor, Moody's, and Fitch. We also test for a relationship between economic freedom and the ratings by these three agencies individually. With a sample covering all 50 states for the period 1995–2008, the evidence strongly indicates that state bond ratings are positively and significantly related to overall economic freedom as well as three sub‐categories of economic freedom. Our results show that the quantitative impact of economic freedom on bond ratings is comparable to the effect of state real income and the unemployment rate. (JEL E43, H71)     

Risk adjusted discount rates and the present value of risky costs

In capital budgeting the correct risk adjusted discount rate for future cash flows is independent of whether the flow is a cost or a revenue. Contrary to a widely disseminated view in some popular textbooks and elsewhere, costs are not especially safe (nor risky), and accordingly costs should not be discounted at especially low risk adjusted discount rates. This paper analyzes capital budgeting within a portfolio model in which revenues and costs appear as “long’ and “short’ portfolio positions, respectively, and proves that costs are neither more nor less intrinsically risky than revenues.
