We formulate a model in which agents embedded in an exogenous social network decide whether to adopt a new network product or not. In the theoretical part of the paper, we characterize the stochastically stable equilibria for complete networks and cycles. For an arbitrary network structure, we develop a novel graph decomposition method to characterize the set of recurrent communication states, which is a superset of stochastically stable equilibria of the adoption game presented in our model. In the simulation part, we study the contagion process of a network product in small-world networks that systematically represent social networks. We simulate a generalization of the Morris (Rev Econ Stud 67(1):57–78, 2000) Contagion model that can explain the chasm between early adopters and early majority. Our numerical analysis shows that the failure of a new network product is less likely in a highly cliquish network. In addition, the contagion process reaches to steady state faster in random networks than in highly cliquish networks. It turns out that marketers should work with mixed marketing strategies, which will result in a full contagion of a network product and faster contagion rates with a higher probability.
We review developments in conducting inference for model parameters in the presence of intertemporal and cross‐sectional dependence with an emphasis on panel data applications. We review the use of heteroskedasticity and autocorrelation consistent (HAC) standard error estimators, which include the standard clustered and multiway clustered estimators, and discuss alternative sample‐splitting inference procedures, such as the Fama–Macbeth procedure, within this context. We outline pros and cons of the different procedures. We then illustrate the properties of the discussed procedures within a simulation experiment designed to mimic the type of firm‐level panel data that might be encountered in accounting and finance applications. Our conclusion, based on theoretical properties and simulation performance, is that sample‐splitting procedures with suitably chosen splits are the most likely to deliver robust inferential statements with approximately correct coverage properties in the types of large, heterogeneous panels many researchers are likely to face. 相似文献
To be competitive and successful in congress tourism, destinations must learn which congress tourism-related attributes are important and how they perform against their main competitors. This study identifies the importance and performance of destination attributes in Antalya, Turkey, and compares the position of these attributes to those of its main rival in congress tourism, ?stanbul. Importance performance competitor analysis results show that, according to domestic participants, Antalya has to focus on “sight-seeing and cultural attractions” and “outside entertainment.” For international participants, “climate,” “choice of meeting and housing properties,” and “suitability of conference facilities” exhibit higher performance in Antalya than ?stanbul. 相似文献
This article investigates the evolution of the monetary transmission mechanisms in Turkey for the period from January 1986 to December 2016. To this aim, the impacts of monetary variables on the prices and economic activity are investigated with a time-varying vector autoregressive model based on. The evidences from the time-varying responses indicate that the adoption of inflation targeting policy has markedly affected the functioning of transmission channels. The results also suggest that local and global financial crises may magnify the impact of monetary policy shocks on the overall economy. 相似文献
Substantial decline in oil prices observed since the second half of 2014 has brought forward discussions on the impact of oil prices on the external balance. This decline is expected to shift real income from oil exporter countries to oil importer countries. In this context, we study the effect of change in oil prices on Turkey’s exports taking into account the fact that Turkey’s export to oil exporting countries has approximately one-third share in total exports, while export to oil importing countries has a share of two-thirds. At the first step, we analyse the effect of oil prices on economic growth of trade partners of Turkey, where countries are grouped according to their net oil export position. We find that the effect of oil prices on different country groups’ growth is asymmetric. In the second stage, for two groups of countries, we estimate growth-export elasticity through Turkey’s export demand function. Finally, we calculate the net effect of oil prices on exports considering different income effects caused by oil price change on each country groups. Results indicate that the net effect of oil prices on the exports is limited given the current export shares. 相似文献
Are hedging transactions that diversify a manager’s compensation risk detrimental to incentives, or can they improve contracting efficiency? If hedging provides efficiency benefits, should the manager or the firm undertake it? In our model, both the firm and the manager can trade financial portfolios to diversify the manager’s compensation risk. Prior to the portfolio selection, the parties need to acquire information on how different financial portfolios fit their diversification purposes. We illustrate that financial portfolios correlated with firm‐specific risk improve contracting efficiency. For equal information costs, it is optimal for the firm to undertake the hedging on the manager’s behalf. 相似文献
This paper suggests a framework for acquisition of new manufacturing technology that links the manufacturing strategy, market requirements and manufacturing attributes using an expert system approach. This paper takes a closer took at traditional notion of manufacturing-marketing coordination and attempts to find its links with manufacturing capabilities provided by recent evolving new manufacturing technology. For this purpose we deal with different steps involved in the strategic evaluation process beginning with the choice of a suitable competitive strategy by a firm. Then the chosen competitive strategy is linked with the market requirements, system attributes and appropriate manufacturing technology choices. The proposed model is integrated by an expert system approach that includes strategic factors of both a tangible and an intangible nature and is implemented by using the VP-Expert shell. 相似文献
This article analyses the development and marketing of Islamic gated communities in Basaksehir, Istanbul. It demonstrates how a blueprint of public–private urban development was appropriated by middle‐class Islamists. The gated communities in Basaksehir—which, at the outset, were not explicitly religious—gradually became attractive to religious actors searching for enclosed urban enclaves where Islamic communities would be protected against perceived moral‐urban threats. While urban‐religious enclaves appear to bear similarities to pre‐modern Ottoman Islamic urban enclaves, the rise of contemporary Islamic gated communities should be understood in light of the recent coming to power of the Islamist Turkish government. In cooperation with this government, housing development agencies approached Islamic investors to find capital for their public–private housing projects. One of the results of this form of urban development is that, contrary to pre‐modern Ottoman Islamic urban enclaves, the Islamic gated communities are homogenous in terms of economic class, catering specifically to the Islamic middle classes. Moreover, people who invest in Basaksehir desire an urban‐religious lifestyle that differs from the ‘traditional' religious lifestyle experienced in ‘traditional' Islamic neighbourhoods. The specific urban‐religious configuration generates a new type of Islam that better fits middle‐class values and a middle‐class lifestyle. 相似文献
This study analyzes the impact of organizational culture and empowerment on innovation capability, and examines the peculiarities of these effects. The study's hypotheses are tested by applying both individual and firm‐level analyses to survey data collected from 743 employees from 93 small and medium‐sized firms located in Turkey. For medium‐sized enterprises on both the individual and firm level of analysis, results suggest that collectivism and uncertainty avoidance are positively associated with empowerment, whereas power distance is negatively related to empowerment. Assertiveness focus has no relations with empowerment and innovation capability, yet among cultural dimensions, only uncertainty avoidance is related to innovation capability. For small‐sized enterprises, findings suggest that both power distance and uncertainty avoidance are linked to both empowerment and innovation capability on the individual level, whereas two new paths between collectivism and innovation capability and between assertiveness focus and empowerment are found on the firm level. Also, empowerment is found to be positively related to innovation capability for both small and medium‐sized enterprises (SMEs) on both the individual and firm level. In terms of managerial practice, our study helps clarify the key role played by cultural dimensions in the process of shaping an empowering and innovative work environment. Findings also reveal that managers should focus on participative managerial practices (e.g., empowerment) to promote innovation capability of SMEs. 相似文献
