Article An Empirical Study of Sequential Offer Bargaining During the Festival of Sacrifice(Elsevier, 2024) Dindaroğlu, Burak; Ertaç, SedaWe report results from a unique data set of real -life bargaining transactions collected from the market for livestock (sheep) before the Festival of Sacrifice (Eid al-Adha) in Izmir, Turkey. This market is characterized by frequent and aggressive bargaining, which occurs in the form of sequential price offers. We record bargaining transactions as they occur, and collect detailed information on the bargaining environment, as well as on the characteristics of buyers and sellers. We also elicit each seller's outside option by means of an incentive compatible mechanism and obtain a reported maximum willingness to pay from buyers. We particularly focus on aspects of the bargaining process, such as non -price communication. In different types of empirical analysis, results robustly indicate that the presence and content of communication matters, for the likelihood of a sale as well as concessions made. Specifically, buyer -side communication is associated with larger concessions from the seller and a higher probability of sale. The presence of a mediator during the negotiation is associated with a higher probability of sale as well, while it has no effect on prices. We also provide results on the relative importance of groups of variables for predicting bargaining outcomes, which can provide directions for further research in bargaining.Article Interpersonal Trust, Invention, and Innovation Across European Regions(John Wiley and Sons Inc, 2023) Dindaroğlu, BurakMany studies in economics and regional science claim a positive link between interpersonal trust and innovation by demonstrating a positive effect of trust on patenting. This contrasts many findings from organization level studies on trust and innovation, who report a variety of findings including inverted-U type relations. A possible explanation is that trust exhibits different roles in invention and innovation, as the former relies on knowledge commons while the latter directly embeds commercialization and the market context. This study attempts to reconcile the two set of findings by studying indicators of invention and innovation in relation to trust at the same unit of observation, by using the regional variation in Europe. I study the relationship between interpersonal trust and patent applications (a measure of invention), trademark applications (a composite indicator) and the share of innovative sales in turnover by SMEs (a direct indicator of commercialization), across European regions. I show that trust positively affects trademark applications with an effect that is comparable to that on patent applications. However, trust exhibits an inverted-U type relationship with innovative sales. Results collectively point to a strong role of trust in all three creative activities, including a negative effect at the higher end when the indicator is directly contingent on commercialization and sales. I also estimate the extent of spatial spillovers in the effect of trust on all three creative outcomes. © 2023 Wiley Periodicals LLC.Article Product Design in Monopolistic Competition(Wiley, 2022) Dindaroğlu, BurakWe consider a model of monopolistic competition where producers can manipulate an elasticity parameter at an early stage. We interpret this as a choice of product specialization. Lower marginal costs of production lead to more generic products in all equilibria, which lead to fewer varieties under free-entry. Entry of a new firm increases overall specialization and increases prices, that is, the environment exhibits price-increasing competition. The loss of consumer surplus due to higher prices and lower consumption is compensated by the value of additional variety, hence entry also increases consumer surplus. Therefore, price-increasing competition need not be anticompetitive under endogenous specialization.Article Citation - WoS: 2Citation - Scopus: 2Regional Inflation Persistence in Turkey(John Wiley and Sons Inc., 2021) Duran, Hasan Engin; Dindaroğlu, BurakThe purpose of the current study is to investigate the degree of inflation persistence, its geographical variation, sources of cross-regional variation, and presence of geographical/sectoral aggregation bias in national monetary policy. Our data set covers 26 NUTS-2 level Turkish regions and monthly CPI inflation over the period 2003-2019. We first estimate the degree of regional inflation persistence by autoregressive regressions, check its robustness against the presence of structural breaks (by Bai-Perron's algorithm) and nonlinearities (by Markovian Regime Switching regressions). Second, we examine the possibility of geographical and sectoral aggregation bias. Third, we investigate the cross-regional determinants of inflation persistence by panel data analysis, employing hybrid-effects spatial panel regressions. We analyze the direct and indirect effects of the determinants and test for regional spillover effects. Three main results are obtained. First, estimated persistence degrees are heterogeneous across regions. The geographical pattern is empirically robust against structural breaks and nonlinearities. We find that inflation persistence is distributed in a spatially correlated manner. Second, when sectoral and regional aggregation bias is tested, only sectoral aggregation indicates a considerable level of bias. Third, we find that the presence of large firms in the region and a higher share of agricultural output in GDP leads to lower persistence, while an increased share of industrial output, and increased trade volume leads to higher inflation persistence. Moreover, we find spatial spillovers of price variability evident in regression analysis. From a policy standpoint, it is required that structural policy programs are targeted to maintain flexibility in the regions where persistence is high (i.e., providing market entry/exit, institutional quality, policy credibility, stimulation of SMEs). Moreover, sectors that have high persistence, such as Hotels and Restaurants (persistence degree 0.55) and Health Services (0.39) should be weighted more in CPI calculations.
