Limit-pricing as Bertrand equilibrium

Summary. We consider a Bertrand duopoly model with increasing returns to scale where one of the firms have a cost advantage and prices vary over a grid. We find that typically more than one equilibria exist. However, there are only two perfect equilibria. Moreover, as the size of the grid becomes small, both these equilibria converge to the limit-pricing outcome. Received: February 25, 2000; revised version: January 9, 2001     

The All‐Pay Auction with Nonmonotonic Payoff

I model innovation contests as an all‐pay auction in which it is possible not to achieve successful innovation despite costly R&D investments, and as a result, there is no winner. In such a case, the winning payoff turns out to be nonmonotonic in own bid. I derive the sufficient conditions for the existence of pure strategy equilibria, and fully characterize the nondegenerate mixed strategy equilibrium. In the mixed strategy equilibrium, the support of the low‐value bidder is not continuous, and both the high‐value and the low‐value bidders place an atom in the (distinct) lower bound of their respective support. Under symmetric valuation, both bidders place an atom at zero. These results can explain why one does not observe very low quality innovation in real life, or why even symmetric firms may stay out of an innovation contest.     

Could lean practices and process innovation enhance supply chain sustainability of small and medium‐sized enterprises?

Small and medium‐sized enterprises (SMEs) adopt lean practices (LP) to reduce waste across their organisational value chain, which helps achieve sustainability. Process innovation (PI) has also been applied through cleaner production, environmental management system, ecodesign, and so on to address both customers' needs and legislations by policymakers. Although prior studies reveal the effect of sustainable practices, LP, and PI on sustainable performance separately, less is known on the integrated effect of them on sustainability performance. Moreover, studies on mediating effect of LP and PI on sustainability performance are scant. This is significant as LP and PI are considered to be the enablers for achieving sustainability performance. This research addresses this knowledge gap. The research first theorises a model integrating these four major constructs (sustainability practices, LP, PI, and sustainability performance) through hypotheses development. Subsequently, using structural equation modelling, it is tested whether each of sustainability practices, LP, and PI effect sustainability performances. Additionally, mediating effect of LP and PI between sustainability practices and performances is derived. The study uses data from 119 SMEs within manufacturing industries in the Midlands, United Kingdom. Further, a few case studies have been undertaken to validate the findings from quantitative analysis. The overall results show that although sustainability practices, LP, and PI help achieve sustainability performance of SMEs supply chain through efficiency and responsiveness respectively, the mediating effect LP is more compared with PI. Moreover, SMEs adopt LP when they are economy focused and implement PI when they are pressurised by customers and/or policymakers.     

REGIME DEPENDENT EFFECT OF OUTPUT GROWTH ON OUTPUT GROWTH UNCERTAINTY: EVIDENCE FROM OECD COUNTRIES

This paper studies the impact of output growth on output growth uncertainty by considering two important issues hitherto not properly and adequately addressed to in the existing empirical studies specifying this relationship. These are: (i) the possible existence of a threshold level of output growth, and the consequent identification of two regimes characterized by high and low output growth, and (ii) whether or not the coefficient capturing the causal link is different in these two output growth states. This paper proposes a regime switching model to study this asymmetric effect for 16 OECD countries. Based on monthly time‐series observations, our results strongly support that the impact varies significantly between the two output growth regimes with the coefficient in the high growth regime being negative for majority of the countries.     

Rana Plaza Fieldwork and Academic Anxiety: Some Reflections

The Rana Plaza collapse, which took place in Bangladesh in 2013, killed and injured at least 1135 and 2500 people respectively. Although the structural fault with the building had been identified before the collapse, the owner of the building and five garment factories housed in Rana Plaza had forced workers to continue production for 31 Western multinational corporations (MNCs). It was the deadliest structural failure in modern history, and resulted in a horrific rescue operation. First, the fire brigade did not have the necessary training and equipment to rescue the victims, and so the general public also participated in the rescue operation. Second, when victims were rescued, it was found that many of them had lost their limbs or suffered severe internal injuries, including internal organ failure, due to several days without water. After the completion of the rescue, the victims received neither appropriate compensation nor rehabilitation to overcome their psychological trauma and physical disabilities.     

OVERBIDDING AND HETEROGENEOUS BEHAVIOR IN CONTEST EXPERIMENTS: A COMMENT ON THE ENDOWMENT EFFECT

We revisit the meta-analysis of Sheremeta on overbidding in contest experiments and focus on the effect of endowment on overbidding. Sheremeta assumes, and finds evidence of, an increasing linear relationship between endowment and overbidding, Quantal Response Equilibrium (QRE) predicts an increasing concave relationship, while Baik and colleagues find an inverted U-shaped relationship in their analysis of a single experiment. We use the same data as in Sheremeta, but employ a different econometric model which leads to support for both QRE and the inverted U-shaped relationship. Following Baik and colleagues, we posit that the inverted-U relationship may be interpreted in terms of a wealth effect.     

Joint-Liability in Microcredit: Evidence from Bangladesh

The joint-liability lending model in microcredit predicts social ties between groups of borrowers to incentivise repayment. However, it also promotes free riding behaviour. Repeated experimental games conducted in Bangladesh are used to empirically analyse key theoretical hypotheses predicted under joint-liability (repeated experimental games are conducted by the author on the field in Manikganj, Dhaka, Bangladesh in December 2014); treated groups of microcredit borrowers are compared to control groups of non-microcredit borrowers alongside questionnaire findings. Treated individuals forego short-run gains from non-repayment and benefit from higher long-run gains from progressing on to further rounds. The paper also finds that treated individuals are significantly less likely to free ride and more likely to shoulder for their partner compared to control individuals. Optimal individual and group characteristics to maximise repayment under joint-liability are then identified.     

Environmental dynamism,human resource flexibility,and firm performance: analysis of a multi-level causal model

While strategic HRM scholars have conceptualized HR flexibility as an important source of sustainable superior firm performance in dynamic environments, the process through which HR flexibility creates value for the firm has not been empirically investigated. Based on a study of 98 manufacturing and 103 service firms from a wide array of industries in India, this paper attempts to illuminate the black box of causal linkages between environmental dynamism, flexibility of human assets, and firm level human-, operational-, and financial-outcomes by developing and testing a multi-level causal model. Evidence indicates that HR flexibility mediates the influence of environmental dynamism on firm performance and that irrespective of the nature of the industry and the degree of environmental turbulence, superior firm performance ensues when HR flexibility as actually possessed by the firm matches the environmental demands for such flexibility as perceived by the firm managers. The results also support the notion of HR value chain that postulates that HR system has direct impact on firm-level HR outcomes which are most proximal, and its effects on increasingly more distal operational- and financial-outcomes are mediated by HR outcomes. The findings of the study suggest that HR practices as a system have both direct and indirect (mediated by behavioral flexibility) effects on firm-level HR outcomes. Existence of significant direct effects signifies that HR practices play an important role as a structural mechanism in achieving superior firm performance.     

FDI and Growth: What Causes What?

This paper examines the causal relationship between FDI and economic growth by using an innovative econometric methodology to study the direction of causality between the two variables. We apply our methodology, based on the Toda‐Yamamoto test for causality, to time‐series data covering the period 1969–2000 for three developing countries, namely Chile, Malaysia and Thailand, all of them major recipients of FDI with a different history of macroeconomic episodes, policy regimes and growth patterns. Our empirical findings clearly suggest that it is GDP that causes FDI in the case of Chile and not vice versa, while for both Malaysia and Thailand, there is a strong evidence of a bi‐directional causality between the two variables. The robustness of the above findings is confirmed by the use of a bootstrap test employed to test the validity of our results.
