The impact of income diversification among fishing communities in Western Kenya

Past studies have shown that fishing communities in developing countries are generally poor. One potential strategy for reducing poverty among these communities is income diversification. This study investigates the impact of income diversification on incomes of fishing communities living on the Kenyan shores of Lake Victoria. Using four propensity score matching methods, we find evidence that income diversification increases the incomes of fish workers. The strongest impact appears to be among fishers, fish enterprise employees and fish workers in the non-export beach. Based on these results, income diversification can be considered a poverty reduction strategy among fishing communities in Western Kenya.     

The impact of high value markets on smallholder productivity in the Ecuadorean Sierra: A Stochastic Production Frontier approach correcting for selectivity bias

This paper uses data from small-scale potato farmers in Ecuador to examine the impact of the program Plataformas de Concertación on productivity growth. Using propensity score matching combined with a Stochastic Production Frontier model that corrects for sample selection bias, we disaggregate the yield growth attributable to the program into technological change (TC) and technical efficiency (TE). While the results do not exhibit a clear indication of selection bias, the analysis does show that on average beneficiaries exhibit higher yields than control farmers given the same input levels, but lower TE with respect to their own frontiers. These results suggest that while the program raised the technology gap in favor of beneficiaries, it had a negative effect on TE in the short run. The latter finding is consistent with the notion that beneficiaries enjoyed a significant change in production techniques, but it is very likely that they were still in the “learning by doing” stages at the time the data was collected. In fact, the results suggest a fast recovery in TE levels on the part of beneficiaries as time with project increased.     

Firm-specific time preferences and postmerger firm performance

This study investigates the role of firm-level discount factors in evaluating the impact of mergers on market outcomes. Discount factors reflect time preferences for future cash flows and are used to determine the present value of investment projects such as mergers. Firm-specific discount factors imply that firms may attach different present values to mergers. We elicit firm-specific time preferences and identify firms’ discount factors using firm-specific production data while building on the existence of learning-by-doing in the semiconductor industry. Our estimation results show that firm-specific discount factors explain firms’ production decisions. We also find that firms’ discount factors and merger acquisition strategies explain heterogeneous merger outcomes. Our results show that acquiring firms characterized by low discount factors (impatient firms) are highly efficient and merge with highly efficient and innovative firms. Impatient acquirers achieve relatively higher efficiency gains in the short run than patient acquirers and adopt acquisition strategies that put more weight on achieving instant efficiency gains. In contrast, patient acquirers are least efficient and merge with firms that are larger than themselves. Patient acquirers place more value on achieving efficiency gains in the more distant future.     

Hybrid cooperation agreements in networks: The case of the airline industry

This paper develops a unified framework to analyze a continuum of hybrid cooperation agreements along two dimensions: their degree of revenue sharing (scope of alliances) and their degree of cost sharing (scope of joint ventures). The analysis focuses on the air transportation industry, distinguishing between interline and interhub markets. As economies of traffic density become stronger, we find that the socially optimal cooperation agreement moves from full alliance to joint venture in interline markets, whereas it moves from joint ventureto merger in interhub markets. These results are driven by the tradeoff between a procompetitive effect of alliances in interline markets and an anticompetitive effect in interhub markets, along with the efficiency gains associated with joint ventures in interhub markets. We also develop an empirical application for intercontinental routes for the period 2010–2016 that identifies a positive impact of deeper degrees of airline cooperation (revenue and cost sharing) on traffic, both in interline and interhub markets. Therefore, the potential anticompetitive effect of deeper alliances in interhub markets is not observed in our sample.     

Estimating Differential Dynamic Merger Effects on Market Structure and Entry in Related Markets

The U.S. and EU merger guidelines emphasize “ease of entry” arguments but little is known about the dynamic impact of realized mergers on market structure. This study provides insights on this topic with the use of detailed firm-level data on the memory chip market. Our estimation results provide evidence for differential merger effects on market structure. These effects depend on whether the mergers are dominated by market-power or efficiency gains. While efficiency-dominated mergers cause exit, market-power-dominated mergers attract entrants, and these effects are increasing over time. We also find that market-power mergers have a larger effect on entry than efficiency mergers have on exit. Our results show that mergers can reduce the number of potential entrants into related product markets and serve as an instrument to “reduce the likelihood of entry”.

     

How to reduce opportunism through contractual governance in the cross-cultural supply chain context: Evidence from Chinese exporters

Opportunistic behavior has been the main threat in cross-cultural supply chains. Drawing on institutional theory, we investigated how Chinese export firms facing cultural differences reduce foreign distributors' opportunism through differentiated contract governance strategies. Based on both a survey dataset of 206 Chinese export firms and a secondary dataset, our results suggest that cultural distance increases opportunism by inhibiting contract application but also decreases opportunism by enhancing detailed contract design. In addition, we found that both indirect effects of cultural distance on opportunism via contract governance strategies depend on the surrounding institutional environment in cross-cultural supply chains. Regulatory uncertainty strengthens the positive impact of cultural distance on detailed contract design and strengthens the negative impact of cultural distance on contract application. Moreover, regulatory uncertainty also strengthens the negative impact of detailed contract design on opportunism and weakens the negative impact of contract application on opportunism.     

Subjective Distance and Team Collaboration in Distributed Teams

This paper challenges the conventional wisdom that objective distance between team members (e.g., measured in miles) translates directly and fully into subjective distance (i.e., a team's perception of distance between its members). Drawing on social information processing theory, we argue that the level of subjective distance is likely to predict important team outcomes better than the level of objective distance. Using responses from 678 team leaders and team members pertaining to 161 new product development projects in the software industry, our results show that the subjective perception of distance is affected rather by team members' national diversity than their physical distance. We also find that subjective distance has a significant impact on team collaboration, while objective distance measures, however, have no impact on team collaboration. Implications for theory and practice are discussed.     

Moving toward the EU or the Middle East? An assessment of alternative Turkish foreign policies utilizing the GTAP framework

This paper assesses the new orientation in Turkish foreign policy towards the Arab world by analyzing the potential impact of Turkey’s membership in either the European Union (EU) or the Greater Arab Free Trade Area (GAFTA). We utilize the most recent version of the Global Trade Analysis Project (GTAP) database, its global Computable General Equilibrium (CGE) model, and the gravity border effect approach to estimate the ad-valorem tariff equivalents (AVEs) of non-tariff barriers (NTBs). In our overall analysis, we account for 24 various sectors. However, in our evaluation, we focus primarily on the food and agricultural sectors because this sector is characterized by high tariff and non-tariff protection. In the CGE simulation analysis, we consider the removal of tariffs and NTBs simultaneously. After projecting the GTAP framework to 2020, we conclude that Turkey would gain unambiguously from EU membership, whereas Turkey’s gains from GAFTA membership would be more limited. The paper also presents that the welfare gains from the removal of NTBs are of considerable importance and would generally be greater than the gains stemming from the elimination of import tariffs.

Structure and dynamics of fertilizer subsidy: The case of Bangladesh

Economists often proceed with impact studies of fertilizer subsidy without first making an examination of the structure and dynamics of subsidy. This may lead to misleading focus and to seeking solutions generally in adjustment of administered prices. Substantial gains in efficiency can be realized by looking into structural questions of subsidy. The case of Bangladesh provides an example of how a proper procedure of accounting can shift the onus of correcting numerous distortions that arise from current practices, from farmers to industries. The case study also shows that farmers receive less subsidy than usually claimed and the hidden subsidy to industries is passed on to farmers. The Bangladesh case may represent developing countries in a general manner.     

Do remedies affect the efficiency defense? An optimal merger-control analysis

This paper examines the optimal use of remedies and the efficiency defense for merger control. We develop a framework in which merger efficiency gains are endogenously determined and are not observed by the Competition Authority. The possibility of an efficiency defense can push firms to design the merger better, leading to greater efficiency gains. Firms can also submit remedies to the Competition Authority: they interact with the efficiency defense, by reducing the firm's incentive to enhance efficiency. At the same time remedies improve the assessment of the merger, in particular by signaling the true level of efficiency gains. We ask to what extent it may be optimal to make use of both instruments simultaneously, and thus discuss the possibility that the Competition Agency refrain from using one of the instruments to try to improve overall merger-control performance.

Location and competition in retail banking

We investigate the impact of banking deregulation during the 1990s on consumer welfare. We estimate a spatial model of consumer demand for retail bank deposits that explicitly accounts for consumer disutility from distance traveled. This is important given the substantial changes in banks' branch networks observed in the data. Our model indicates that cross-price elasticities between banks whose branches are close to consumers (‘close’ banks) are larger than those between ‘far’ banks and more than double the cross-price elasticity of ‘close’ banks with respect to ‘far’ banks. We distinguish between thrifts and other banks and find that within-thrift competitive effects are stronger than within-bank effects or those between thrifts and banks. We use our estimates to predict the effect of changes in market structure on consumer welfare following the branching deregulation of the Riegle–Neal Act of 1994. Our results indicate that the median household gained around $60 per year from the changes. Approximately two thirds of the gains come from within-market changes in market structure. The gains were greater in markets with high initial numbers of banks than elsewhere.     

Perception by French students of the gendered nature of material artifacts studied in technology education

Many studies have shown the importance of the socio-cultural factors that lead girls to desert scientific and technological courses. Over a long period, the contents of the French technology education (TE) college curricula may well have contributed to strengthening the feeling among girls that this discipline was better suited to boys. The choice of technical artifacts that embody the knowledge taught could be partially responsible for this. Our investigation was conducted in two stages. Firstly, we made an inventory of artifacts presented in four TE schoolbooks for the 6th grade. Secondly, we submitted this list to a population of 98 girls and boys (12–14 years). Our results indicate that most of these artifacts were categorized as mixed. However, those that are classed as masculine are more numerous than feminine one’s. They are also more prevalent among girls and their number increases with age. The grouping of these artifacts by families also shows gender differences.     

Entry in the ADHD drugs market: Welfare impact of generics and me‐too's

Recent decades have seen a growth in treatments for attention deficit hyperactivity disorder (ADHD) including many branded and generic drugs. In the early 2000's, new drug entry dramatically altered market shares. We estimate a demand system for ADHD drugs and assess the welfare impact of new drugs. We find that entry induced large welfare gains by reducing prices of substitute drugs, and by providing alternative delivery mechanisms for existing molecules. Our results suggest that the success of follow‐on patented drugs may come from unanticipated innovations like delivery mechanisms, a factor ignored by proposals to retard new follow‐on drug approvals.     

A retrospective study on the regional benefits and spillover effects of high-speed broadband networks: Evidence from German counties

This study aims to assess the economic benefits of high-speed broadband within and across neighboring counties in Germany. Utilizing a balanced panel dataset of 401 German counties with data from 2010 to 2015 as well as different panel estimation techniques, we find that an increase in average broadband speed has a significantly positive effect on regional GDP in the average German county. Furthermore, we find that broadband deployment in German counties induces not only substantial economic benefits in terms of direct effects within counties but also positive regional externalities across counties. According to our estimation results, an increase in average bandwidth speed by one unit (1 Mbit/s) induces a rise in regional GDP of 0.18%. This effect is almost doubled if we also take regional externalities into account (0.31%). Moreover, we find that regional agglomeraton effects are of particular relevance for rural counties. Our cost-benefit analysis of subsidies based on conservative estimates suggests efficiency gains, as the total economic per capita benefits (€164) of subsidy programs to encourage broadband expansion exceeded their associated per capita costs (€114).     

Quantifying the benefits of the introduction of the hybrid electric vehicle

This study models demand and supply in the market for new automobiles to estimate the economic benefits generated by the introduction of the hybrid electric vehicle. We estimate our model using all new vehicle registrations in California along with detailed demographic data. Our counterfactual analysis reveals that the addition of hybrids to the consumer choice set generates gains in social surplus that peak at roughly $1.2 billion annually in 2007, but environmental benefits make up 0.2% of the net benefits. We find that 31% of the social surplus in 2008 can be attributed directly to the hybrid vehicles independently from gains in fuel efficiency, with the remaining 69% attributed to the gains in fuel efficiency. We further show that all income groups benefit from the introduction of the hybrids, with the top 50% of the income distribution receiving the most.     

Types of R&D Collaborations and Process Innovation: The Benefit of Collaborating Upstream in the Knowledge Chain

This paper explains how research and development (R&D) collaborations impact process innovation; given the differences in innovation mechanisms, prior insights from studies of product innovation do not necessarily apply to process innovation. Extending the knowledge‐based view of the firm, this paper classifies four types of R&D collaborations—with universities, suppliers, competitors, and customers—in terms of two knowledge dimensions: position in the knowledge chain and contextual knowledge distance. Position in the knowledge chain is the position of the R&D collaboration partner in the knowledge chain of the industry—the input–output sequence of activities that result in the transformation of raw materials into products that are used by end customers. Based on this knowledge chain, this paper considers universities and suppliers as upstream R&D collaborators, and competitors and customers as downstream R&D collaborators. Contextual knowledge distance is the difference in industry‐related contexts of operation of the R&D collaboration partners and the firm. Based on this, this paper views R&D collaborators that are suppliers and competitors as having low contextual knowledge distance to the firm, and R&D collaborators that are customers and universities as having high contextual knowledge distance to the firm. Using this classification, this paper proposes a ranking of R&D collaborations in terms of their impact on process innovation: R&D collaborations with suppliers have the highest impact, followed by R&D collaborations with universities, then R&D collaborations with competitors, and finally R&D collaborations with customers. These arguments are tested on a four‐year panel of 781 manufacturing firms. The results of the analyses indicate that R&D collaborations with suppliers and universities appear to have a positive impact on process innovation, R&D collaborations with customers appear to have no impact, and R&D collaborations with competitors appear to have a negative impact. As a consequence, the main driver of the impact of R&D collaborations on process innovation appears to be position in the knowledge chain rather than contextual knowledge distance. These novel ideas and findings contribute to the literature on process innovation. Even though process innovation tends to be internal and tacit to the firm, it can still benefit from external R&D collaborations; this paper is the first to analyze this relationship and provide a theoretical framework for understanding why this would be the case. This study also has important managerial implications. It suggests that managers need to be careful in choosing the partners for their firms' R&D collaborations. Engaging in R&D collaborations with universities and suppliers appears to be helpful for process innovation, whereas conducting R&D collaborations with competitors may potentially harm process innovation.     

ICTs quality and technical efficiency: An empirical analysis

In 1987, Robert M. Solow hinted at the computer age and productivity statistics puzzle. While this puzzle persisted for many years, a growing literature has picked it up to examine the effect of ICTs on technical efficiency. However, this literature has focused mainly on quantity-based ICTs measures, which have come under severe criticism in recent times. We advance this literature in this paper by shifting the focus of analysis to quality-based ICTs measures; in this case, Internet quality. We also extend the literature by examining how the envisaged relationship between ICTs quality and technical efficiency is conditioned by a country's unique attributes. Our results show a significantly positive effect of ICTs quality on technical efficiency. We also find that the technical efficiency gains associated with ICTs quality are higher in skill-abundant countries, countries that engage more intensively in cross-border trade, have stronger contracting institutions, and are endowed with well-functioning and well-developed financial markets that ensure greater efficiency of capital allocation. We find a network effect in the nexus between ICTs quality and technical efficiency. That is, the marginal effect of ICTs quality on technical efficiency increases as the number of Internet users expands. We discuss the policy implications of our findings.     

Inflation and Real Estate Investment Value

It is demonstrated that the inflation rate must be reflected in the anticipated benefit flows used in investment value models. When flows are left unadjusted, a biased value estimate results. It is also shown that the actual effects of the inflation rate on investment value will depend on the relationships of original cost, the debt/equity ratio, and the level of depreciation expense. Inflation has a fundamentally negative impact on value traceable to capital gains and depreciation effects. This can be offset by the use of debt financing.
