Public goods in networks

This paper considers incentives to provide goods that are non-excludable along social or geographic links. We find, first, that networks can lead to specialization in public good provision. In every social network there is an equilibrium where some individuals contribute and others free ride. In many networks, this extreme is the only outcome. Second, specialization can benefit society as a whole. This outcome arises when contributors are linked, collectively, to many agents. Finally, a new link increases access to public goods, but reduces individual incentives to contribute. Hence, overall welfare can be higher when there are holes in a network.     

Research cycles

This paper studies the dynamics of fundamental research. We develop a simple model where researchers allocate their effort between improving existing fields and inventing new ones. A key assumption is that scientists derive utility from recognition from other scientists. We show that the economy can be either in a regime where new fields are constantly invented, and then converges to a steady state, or in a cyclical regime where periods of innovation alternate with periods of exploitation. Our analysis provides a rigorous foundation to the Kuhnian theory of scientific evolution. We show that scientists' care for reputation has a strong impact on research dynamics and tends to favor innovation. Especially, innovation fads may emerge. We also study welfare and find that the academic reputational reward system can help align scientists' short-term incentives with society's long-term interests.     

Assessing holiday satisfaction of Australian travellers in Vietnam: An application of the HOLSAT model

The hotel business model has been diversified in response to the various needs of consumers. Many previous studies focused on the alteration factors of the hotel business model from the consumer's point of view. Although it is one of the factors that affect alteration of the hotel business model, the manager's perspective is also an important alteration factor. This article emphasizes that it is necessary to consider not only the consumer side, but also the management side based on two approaches of the strategy theory: the positioning approach and the resource-based approach.

Surveys were conducted by mail in order to gather information regarding what managers in Japan consider to be important components of a hotel. As a result, “location” was found to be the most important component, followed by “annex facilities” and “deployment system”. Once the components were ordered according to their relative importance, a strong relationship was found between the managers' preferences and the characteristics of “syukuhakusyutai-type” hotels, which are ‘direct management’ (DM) hotels located usually in the city. In Japan, the number of “syukuhakusyutai-type” hotels has recently increased, therefore capturing the spotlight in the hotel industry. However, the results of this research are not compared with those of much previous research conducted on hotel choice attributes, because the measured variables differed significantly.     

Strategic timing of earnings announcements?

Using firm‐specific regressions, I show that earnings response coefficient differ across firms. However, there is no evidence of differential earnings response coefficient to a certain earnings announcement time. By switching to a different announcement time from its preferred time, a firm does not gain a softer market reaction. I compare research results from a firm‐specific method and from a pooled time‐series and cross‐sectional method and demonstrate that they differ significantly due to large heterogeneity across firms. I suggest that researchers should adopt a firm‐specific approach to avoid misleading results and to achieve improved estimations.     

Intermediate levels of property rights and the emerging housing market in Ho Chi Minh City,Vietnam

Vietnam introduced a Policy of Renovation (‘Doi Moi’ Policy) to restructure the economy in 1986. Under this policy, the Land Use Right Certificate was introduced as a form of tenure for agricultural land and urban land, according to the Land Laws of 1987 and 1993, respectively. However, by 2001, most properties and/or land in Vietnam still did not have a legal title. Although Vietnam's land reforms in the 1990s provided some of the weakest private rights among the transition countries, big cities like Ho Chi Minh City are presently homes to thriving housing markets. Transactions of ‘property without a physical entity and legal title’ in the real estate market show how property ownership can be formed in order to operate within different institutional contexts. This paper highlights that ‘intermediate levels of property rights’ are the driving forces behind the thriving housing market in Ho Chi Minh City.

FORECASTING STOCK INDEX VOLATILITY: COMPARING IMPLIED VOLATILITY AND THE INTRADAY HIGH–LOW PRICE RANGE

The intraday high–low price range offers volatility forecasts similarly efficient to high‐quality implied volatility indexes published by the Chicago Board Options Exchange (CBOE) for four stock market indexes: S&P 500, S&P 100, NASDAQ 100, and Dow Jones Industrials. Examination of in‐sample and out‐of‐sample volatility forecasts reveals that neither implied volatility nor intraday high–low range volatility consistently outperforms the other.     

Do I know you? How brand familiarity and perceived fit affect consumers’ attitudes towards brands placed in movies

The present study uses Associative Network Theory to construct a model that explains effects of brand placement in movies. Based on a field experiment (n?=?167), we investigate the effects of plot connection and prominence on brand attitude, as well as the mediating role of brand-movie fit and the moderating role of brand familiarity. Results show that more closely connecting a brand to the plot of a movie positively impacts brand attitude by increasing the perceived fit between the brand and the movie. Brand familiarity moderates the effect of the interaction between a placement’s plot connection and prominence on brand attitude. When brand familiarity is high, there is no significant effect of plot connection on brand attitude, nor is this effect moderated by the prominence of the placement. However, when brand familiarity is low, both prominently and subtly connecting the brand to the plot of the movie positively influences brand attitude. More importantly, the effect of plot connection is significantly stronger when an unfamiliar brand is prominently placed, than when it is subtly placed.     

Cultural distance and cross-border bank linkages

This study investigates the effect of cultural distance on global bank linkages using country-pair data for the period 1990–2013. We followed Schwartz (2006) to measure cultural distance, and employed the number of bank pairs involved in cross-border syndicated lending from the source to target countries as a measure of bank linkages. We found that cultural distance has a negative association with bank linkages. This effect is stronger in countries featuring higher informational asymmetries, as represented by weaker institutions, higher uncertainty, or revolution shocks. Our results hold even when employing alternative measures of bank linkages and cultural distance, and when considering the potential endogeneity of cultural distance.     

Customer satisfaction and the cost of capital

Using a sample of U.S. firms from 1995 through 2015 and the customer satisfaction scores from the American Customer Satisfaction Index, we find strong evidence that firms with higher customer satisfaction scores enjoy lower cost of equity capital, even after controlling for other factors that determine the cost of equity. In addition, results from a propensity score matched sample analysis, a difference-in-differences analysis, and instrumental variable regressions suggest that our findings are robust to accounting for endogeneity. We also document that customer satisfaction is positively related to investor recognition and financial report quality. The effect of customer satisfaction on the cost of equity increases with the level of information asymmetry, consistent with customer satisfaction mitigating information asymmetry. Overall, our findings suggest that customer satisfaction lowers a firm’s risk and significantly attenuates its financing costs.
