Exact decomposition of the Fisher ideal total factor productivity index

Decompositions of total factor productivity (TFP) shed light on the driving factors behind productivity change. We develop the first exact decomposition of the Fisher ideal TFP index which contains no debatable mixed-period components or residuals. We systematically isolate five effects of (1) technical change, (2) technical efficiency, (3) scale efficiency, (4) allocative efficiency, and (5) price effect. The three efficiency components (2–4) represent the efficiency of achieving a given target point. Components (1) and (5) capture the changes of the target point. While the technical change component is well-established, changes in the relative input–output prices can have real effects on the scale and scope of the target. Such changes are captured by the new price effect component (5). The new decomposition is compared with existing decompositions both in theory and by means of an empirical application to a panel data of 459 Finnish farms in years 1992–2000.

Joint estimation of technology choice and technical efficiency: an application to organic and conventional dairy farming

This paper proposes an econometric framework for joint estimation of technology and technology choice/adoption decision. The procedure takes into account the endogeneity of technology choice, which is likely to depend on inefficiency. Similarly, output from each technology depends on inefficiency. The effect of the dual role of inefficiency is estimated using a single-step maximum likelihood method. The proposed model is applied to a sample of conventional and organic dairy farms in Finland. The main findings are: the conventional technology is more productive, ceteris paribus; organic farms are, on average, less efficient technically than conventional farms; both efficiency and subsidy are found to be driving forces behind adoption of organic technology.     

Marketing sustainable tourism: the role of value orientation,well-being and credibility

Abstract

Marketing for sustainable tourism primarily attracts customers with a biospheric–altruistic value orientation. To reach a broader consumer group and also persuade people with a self-enhancement orientation to book sustainable hotels, the effectiveness of three different communication styles (emotionality levels, amount of sustainability information and inclusion of a label) is investigated, considering the consumer’s value orientation. An experiment with 337 participants was conducted to analyze the effects of communication on consumer perceptions of well-being and credibility. Multigroup structural equation modeling was used to compare the impacts of communication style on participant’s attitude toward booking a sustainable hotel, mediated by well-being and credibility. The results highlight significantly different communication effects among the two contrasting target groups. Consumers who are highly interested in sustainability (biospheric–altruistic value orientation) are persuaded by messages that include details about the hotel’s sustainability performance, in order to increase the social–environmental well-being, whereas for customers who are less interested in sustainability (self-enhancement value orientation), a self-referential emotionally communication is essential, as it increases the emotional well-being. Inconsistent findings regarding the role of communication in raising the perception of credibility were obtained.     

The warnings puzzle: an upstream explanation

Enforcement agencies issuing warnings are an empirical regularity in the enforcement of laws and regulations, but a challenge to the standard economic theory of public enforcement. A number of recent contributions explain the popularity of warnings as a response to information asymmetries between regulator and regulatee. We offer a distinct, but complementary explanation: Warnings can serve as a signaling device in the interaction between the enforcement agency and its budget-setting authority. By using costly warnings for minor offenses that would otherwise not be pursued, the agency can generate observable activity to escape budget cuts in subsequent periods. We show in a stylized model that warnings may indeed occur in an equilibrium of a game in which warnings are entirely unproductive in the agency-regulatee interaction, and thereby derive a testable hypothesis on regulatory agency behavior.     

The Intergenerational Transfer of Solar Radiation Management Capabilities and Atmospheric Carbon Stocks

Solar radiation management (SRM) technologies are considered one of the likeliest forms of geoengineering. If developed, a future generation could deploy them to limit the damages caused by the atmospheric carbon stock inherited from the current generation, despite their negative side effects. Should the current generation develop these geoengineering capabilities for a future generation? And how would a decision to develop SRM impact on the current generation’s abatement efforts? Natural scientists, ethicists, and other scholars argue that future generations could be more sanguine about the side effects of SRM deployment than the current generation. In this paper, we add economic rigor to this important debate on the intergenerational transfer of technological capabilities and pollution stocks. We identify three conjectures that constitute potentially rational courses of action for current society, including a ban on the development of SRM. However, the same premises that underpin these conjectures also allow for a novel possibility: If the development of SRM capabilities is sufficiently cheap, the current generation may for reasons of intergenerational strategy decide not just to develop SRM technologies, but also to abate more than in the absence of SRM.     

Techno-economic modeling of value network configurations for public wireless local area access

The growing amount of mobile data traffic increases the demand for local area network deployments, and therefore is likely to have an effect on the mobile communications ecosystem. Several alternative value network configurations exist giving new business opportunities to different actors, but the attractiveness and success of local area access provisioning remains uncertain. This article analyzes the business of public local area access from the point of view of two potential providers: service application providers, i.e. companies whose core business is to provide information and content services in the Internet, and mobile operators. A quantitative techno-economic model is constructed to quantify the costs and required revenues of operating viable public local area access networks. The results show that the revenue requirements vary between public venue types and value network configurations.     

Stochastic non-smooth envelopment of data: semi-parametric frontier estimation subject to shape constraints

The field of productive efficiency analysis is currently divided between two main paradigms: the deterministic, nonparametric Data Envelopment Analysis (DEA) and the parametric Stochastic Frontier Analysis (SFA). This paper examines an encompassing semiparametric frontier model that combines the DEA-type nonparametric frontier, which satisfies monotonicity and concavity, with the SFA-style stochastic homoskedastic composite error term. To estimate this model, a new two-stage method is proposed, referred to as Stochastic Non-smooth Envelopment of Data (StoNED). The first stage of the StoNED method applies convex nonparametric least squares (CNLS) to estimate the shape of the frontier without any assumptions about its functional form or smoothness. In the second stage, the conditional expectations of inefficiency are estimated based on the CNLS residuals, using the method of moments or pseudolikelihood techniques. Although in a cross-sectional setting distinguishing inefficiency from noise in general requires distributional assumptions, we also show how these can be relaxed in our approach if panel data are available. Performance of the StoNED method is examined using Monte Carlo simulations.
