Carbon emissions,trade liberalization,and the Japan–ASEAN interaction: A group-wise examination

As in any modern economy, trade is central to the progress of the economy in the Association of Southeast Asian Countries (ASEAN) region, but environmental degradation occurs with globalization. Using panel data from the period 1970–2006, this study examines the interaction between trade and the environment in terms of carbon emissions for the group of ASEAN countries. The results demonstrate that CO₂ emissions display an inverted-S shape in the region. In general, exports as a percentage of the gross domestic product (GDP) are main contributors to carbon emissions in the developed, developing and late-developing ASEAN countries. The study found no evidence for the Foreign Direct Investment’s (FDI) deteriorating impact on environmental quality. Moreover, Japan’s imports from the region do not cause pollution while China’s imports stimulate the pollution per capita.     

The Old‐Boy Network and the Quality of Entrepreneurs

We study a model of network formation and start‐up financing with endogenous entrepreneurial type distribution. A hub firm admits members to its network based on signals about entrepreneurs' types. Network membership is observable, which allows lenders to offer different interest rates to network and stand‐alone entrepreneurs. We show that a network outcome can display a smaller number of high‐type entrepreneurs even though the network is neither nepotistic nor informationally disadvantaged. Although a welfare‐improving network can emerge as a technically stable or unstable equilibrium, one that decreases welfare is always formed by a technically unstable equilibrium. However, the adverse welfare effects of a network and its corresponding type configuration may persist because ex post high‐type entrepreneurs prefer to stay high type whereas those who wish to become high type may need some time to react.     

The change on the foundations of the Turkish accounting system and the future perspective

Accounting is a social construct and shaped by the society in which it operates. Needs of society are the most important influencing factors in the development of accounting in a country. Though in today's open system societies, the change in the accounting is inevitable, it should not be forgotten that accounting is not only a practice but also a discipline which has got theoretical and historical backgrounds. In this regard, this paper notes the changes in Turkish accounting system from the theoretical and historical perspectives.     

Social sources of information in opportunity recognition: Effects of mentors,industry networks,and professional forums

Effects on opportunity recognition of three social sources of opportunity-related information (mentors, informal industry networks, participation in professional forums) were investigated. Results indicated that all three sources had direct, positive effects on opportunity recognition by entrepreneurs. In addition, the effects of two sources (mentors and professional forums) were mediated by schema strength, while effects of the third source (informal industry networks) were mediated by self-efficacy. Results are consistent with theories of opportunity recognition that emphasize the role of information and cognitive processes, and suggest that two social sources of information not systematically investigated in previous research–mentors and participation in professional forums–can assist entrepreneurs in identifying opportunities for new ventures.     

FREE PARKING FOR ALL IN SHOPPING MALLS

We show why a mall provides parking for free and embed the parking costs in the prices of the goods. Essentially, charging a parking fee to risk‐averse customers means penalizing them for not finding their desired good. This result holds whether the mall has monopoly power or prices competitively, if there is parking validation, and if there is a trade‐off between shopping and parking spaces. It is also the attainable social optimum. The equilibrium lot size is too small, yielding a rationale for minimum parking requirements. However, parking fees may be positive and lots may be too large in urban malls.     

Patterns of innovation and intra-industry heterogeneity in Turkey

This study investigates the patterns of innovation in Turkey and its primary aim is to examine the intra-industry heterogeneity in innovative activities. For this purpose double-level factor analysis is performed and the resulting factor scores are used in the subsequent cluster analyses. Four distinct innovation patterns, which may be interpreted as ingredients of different technological regimes, are identified. A taxonomy of innovative firms is also constructed by grouping firms according to their innovation characteristics and, to the authors’ knowledge, this is the first empirical classification study in Turkey. These results indicate that industries differ in terms of innovative activities. However, industries are not dominated by a single technological regime. On the contrary, five technological regimes were observed in almost all sectors. Building upon these facts, it can be speculated that sector-specific conditions determine the extent of intra-industry heterogeneity.     

Manipulation Through Biased Product Reviews*

We study a signal-jamming model of product review manipulation in which rational consumers consult product reviews and price to better estimate a product's quality, and a firm, whose quality is either high or low, chooses its price and how much bias to insert into product reviews. We show that both firm types always exert positive effort to manipulate product reviews, and, depending on the equilibrium price level, one or both of them can increase its sales. When the high-type firm exerts more effort than the low-type, review manipulation benefits consumers by raising [lowering] their demand for the high-quality [low-quality] product.     

Exploring the mediating role of innovation in the effect of the knowledge management process on performance

The aim of this study is to explore the mediating role of innovation components in the relationship between knowledge management processes and performance. The research questions were investigated through questionnaires with top-level managers of a firm operating in the Turkish telecommunication industry. The results of the study indicated that knowledge management processes affect all innovation components. In addition to the direct effects of the knowledge management process on firm performance, marketing, product and process innovation are mediators in the relationship between the knowledge management process and performance. Finally, this research sheds light on how firms can manage their knowledge to gain a competitive advantage based on innovation.     

Metaheuristic-based simulation optimization approach to network revenue management with an improved self-adjusting bid price function

Making accurate accept/reject decisions on dynamically arriving customer requests for different combinations of resources is a challenging task under uncertainty of competitors' pricing strategies. Because customer demand may be affected by a competitor's pricing action, changes in customer interarrival times should also be considered in capacity control procedures. In this article, a simulation model is developed for a bid price–based capacity control problem of an airline network revenue management system by considering the uncertain nature of booking cancellations and competitors' pricing strategy. An improved bid price function is proposed by considering competitors' different pricing scenarios that occur with different probabilities and their effects on the customers' demands. The classical deterministic linear program (DLP) is reformulated to determine the initial base bid prices that are utilized as control parameters in the proposed self-adjusting bid price function. Furthermore, a simulation optimization approach is applied in order to determine the appropriate values of the coefficients in the bid price function. Different evolutionary computation techniques such as differential evolution (DE), particle swarm optimization (PSO), and seeker optimization algorithm (SOA), are utilized to determine these coefficients along with comparisons. The computational experiments show that promising results can be obtained by making use of the proposed metaheuristic-based simulation optimization approach.     

The Effect of Ability on Young Men's Self‐Employment Decision: Evidence from the NELS

Using the National Educational Longitudinal Study data, we examine the role of pre‐market abilities on young men's self‐employment decision. Our results indicate that cognitive and non‐cognitive abilities are two important, in opposing directions, predictors of self‐employment. We also find that cognitive and non‐cognitive abilities may differ in their malleability with the latter being more malleable during adolescence.
