Efficiency–equity tradeoffs and the scope for resource reallocation in agricultural research: evidence from Nigeria

On the basis of projected economic and poverty impacts of alternative commodity research programs, this article assessed efficiency and equity tradeoffs and the scope for research resource reallocation in Nigeria. Given the importance of major food staples to both poor and nonpoor households in production and consumption, introducing a poverty dimension revealed no significant shift in priorities compared with those implied by efficiency. The results showed that neither the additional benefits to the poor nor the foregone benefits to society are significant from prioritizing research according to equity—relative to efficiency—criteria. As current priorities are supported by neither efficiency nor equity criteria, however, there is considerable scope for maximizing research benefits to the poor through informed reallocation of research resources. The article concludes with a discussion of the patterns of resource reallocations implied by efficiency and equity criteria.     

Wolves' contribution to structural change in grazing systems among swiss alpine summer farms: The evidence from causal random forest

The return of wolves to Swiss mountains and the damage they cause to sheep and goat herds in the region have raised concerns about a consequent wave of farm closures. In this paper, we examine the relationship between wolf attacks and the decline of Alpine summer farms, a specific high-altitude farm type. We collected farm structure data and monitoring data on wolf attacks between 2004 and 2021 and analysed them using a causal random forest method, enabling a detailed analysis of the relation between wolf attacks and the number of different types of Alpine summer farms at a regional level. The results show that the farming systems are unaffected by incidental and infrequent wolf attacks, but that a high number of wolf attacks in a region is related to faster decrease in number of grazing systems where sheep are most vulnerable to such attacks. In contrast, systems that allow for better herd protection tend to show an increase in areas with frequent wolf attacks.     

Cultural change that sticks

When a major change initiative runs aground, leaders often blame their company's culture for pushing it off course. They try to forge ahead by overhauling the culture--a tactic that tends to fizzle, fail, or backfire. Most cultures are too well entrenched to be jettisoned. The secret is to stop fighting your culture--and to work with and within it, until it evolves in the right direction. Today's best-performing companies, such as Southwest Airlines, Apple, and the Four Seasons, understand this, say the authors, three consultants from Booz & Company. These organizations follow five principles for making the most of their cultures: 1. Match strategy to culture. Culture trumps strategy every time, no matter how brilliant the plan, so the two need to be in alignment. 2. Focus on a few critical shifts in behavior. Wholesale change is hard; choose your battles wisely. 3. Honor the strengths of the existing culture. Every culture is the product of good intentions and has strengths; put them to use. 4. Integrate formal and informal interventions. Don't just implement new rules and processes; identify "influencers" who can bring other employees along. 5. Measure and monitor cultural evolution. Otherwise you can't identify backsliding or correct course. When the leaders of Aetna applied these rules while implementing a new strategy in the early 2000s, they reinvigorated the company's ailing culture and restored employee pride. That shift was reflected in the business results, as Aetna went from a $300 million loss to a $1.7 billion gain.     

Price competition and reputation in markets for experience goods: an experimental study

We experimentally examine the effects of price competition in markets for experience goods where sellers can build up reputations for quality. We compare price competition to monopolistic markets and markets where prices are exogenously fixed. Although oligopolies benefit consumers regardless of whether prices are fixed or endogenously chosen, we find that price competition lowers efficiency as consumers pay too little attention to reputation for quality. This provides empirical support to recent models in behavioral industrial organization that assume that consumers may, with increasing complexity of the marketplace, focus on selected dimensions of products.     

Board‐Level Employee Representation (BLER) and Firms’ Responses to Crisis

Short: We hypothesize that companies with board‐level employee representation (BLER) experience a lower probability of crisis‐induced dismissals than other firms. Theoretically, we link this effect to the employee directors’ ability to reduce the information asymmetry and moral hazard in employee–employer contracting, thereby facilitating the implementation of labor‐cost adjustments that are an alternative to workforce dismissals. We confirm our hypotheses by analyzing the behavior of Scandinavian public corporations with/without employee directors during the Great Recession.     

Testing the efficiency of the Norwegian housing market

The question of whether or not the housing market is efficient is posed by an increasing number of economists, policymakers, homebuyers, and homesellers. This article tests the efficiency hypothesis on data from the housing market in Oslo over the period 1991–2002, employing the Case–Shiller time-structure test on a repeat-sales house price index and returns to housing. We demonstrate that both the repeat-sales house price index and returns contain time structure and that the housing market is characterized by inefficiencies. We also find, surprisingly, that the housing market consistently yields higher appreciation at lower volatility than the stock market over the period.     

Questioning the relevance of supplier satisfaction for preferred customer treatment: Antecedent effects of comparative alternatives and multi-dimensionality

Through the construct of supplier satisfaction, recent research explains the supplier's preferred treatment of a given customer. This cause-and-effect phenomenon is often not contrasted with other reasons or controlled for. This work addresses this issue and uses two tactics to elaborate upon social exchange theory, namely, construct splitting and construct contrasting, to analyse the development of preferential customer treatment. For this purpose, a structural equation model is used with data from the international automotive industry. The results extend the breadth of constructs explaining preferred customer treatment (PCT) and challenge the existing reasoning by questioning the relative importance of supplier satisfaction. While supplier satisfaction does affect PCT, the relative supplier satisfaction defined as a comparison of outcomes between the actual and the best alternative business relationships influences PCT much more.Furthermore, by distinguishing between the economic and non-economic dimensions of supplier satisfaction, the study indicate that economic satisfaction has a higher influence on the relative satisfaction whereas social satisfaction a higher one on absolute supplier satisfaction.These findings imply that despite the current debate about the importance of behavioural constructs such as supplier interaction and social capital, supplier resource allocation decisions are actually dominated by economic and relative aspects of satisfaction. This outcome calls for a more economically driven debate about behavioural supply management approaches.     

The New Keynesian Phillips curve and the role of expectations: Evidence from the CESifo World Economic Survey

We provide evidence on the fit of the hybrid New Keynesian Phillips curve for selected Euro zone countries, the US and the UK. Instead of imposing rational expectations and estimating the Phillips curve by the Generalized Method of Moments, we use direct measures of inflation expectations from the CESifo World Economic Survey. Our main findings are as follows: (i) The use of survey data gives empirical results, which are more reliable than those obtained from the GMM approach. (ii) The purely forward-looking Phillips curve can be rejected in favor of the hybrid New Keynesian Phillips curve. (iii) The estimated coefficients on past inflation are higher when using survey expectations than when using the rational expectations GMM approach. (iv) It remains unclear whether real unit labor costs or a measure of the output gap should be used as a proxy for real marginal costs. (v) Theory-based restrictions lead to an improvement of the empirical results.     

Playing Cournot although they shouldn’t

Summary. In this note, we experimentally investigate the extended game with action commitment in a Cournot duopoly with asymmetric cost. Risk dominance considerations allow to select a unique equilibrium in which the low-cost firm is the Stackelberg leader. The data, however, do not support the theory as simultaneous-move play is modal. Average output choices are in line with the Cournot equilibrium. This suggests that Cournot is a much more robust predictor for competition in markets than theory suggests.Received: 14 October 2002, Revised: 1 December 2003, JEL Classification Numbers: C72, C92, D43.

Market Power with Interdependent Demand: Sale of Emission Permits and Natural Gas from Russia

With implementation of the Kyoto Protocol, Russia will most likely be able to exert market power in the emission permit market. But, as Russia is also a big exporter of fossil fuels, the incentives to boost the permit price may be weak. However, a significant share of Russia’s fossil fuel exports is natural gas. If a high permit price boosts the demand for natural gas through substitution from more polluting fuels and thus increase gas profits, this may increase the incentives to exert monopoly power in the permit market. Moreover, a large fossil fuel exporter may use its market position to influence the effective demand for permits. Hence, the relationship between permit income and fossil fuels exports runs in both directions. In this article, we explore the interdependence between the revenues from permit and fossil fuel exports both theoretically and numerically. A computable general equilibrium model suggests the fact that Russia as a big gas exporter has small effect on the incentives to exert monopoly power in the permit market. Moreover, Russia’s monopoly power in the permit market has a small, but non-negligible impact on the optimal level of Russian gas exports.
