Observational Learning: Evidence from a Randomized Natural Field Experiment

We present results about the effects of observing others' choices, called observational learning, on individuals' behavior and subjective well-being in the context of restaurant dining from a randomized natural field experiment. Our experimental design aims to distinguish observational learning effect from saliency effect (because observing others' choices also makes these choices more salient). We find that, depending on specifications, the demand for the top 5 dishes was increased by an average of about 13 to 18 percent when these popularity rankings were revealed to the customers; in contrast, being merely mentioned as some sample dishes did not significantly boost their demand. Moreover, we find that, consistent with theoretical predictions, some modest evidence that observational learning effect was stronger among infrequent customers. We also find that customers' subjective dining experiences were improved when presented with the information about the top choices by other consumers, but not when presented with the names of some sample dishes.

Do Multinationals' R&D Activities Stimulate Indigenous Entrepreneurship? Evidence from China's "Silicon Valley"

Using a unique firm-level dataset from China's "Silicon Valley," we investigate how multinational enterprises (MNEs) affect local entrepreneurship and R&D activities upon entry. We find that R&D activities of MNEs in an industry stimulate entry of domestic firms into the same industry and enhance R&D activities of newly entering domestic firms. By contrast, MNEs' production activities or domestic firms' R&D activities do not have such effect. Since MNEs are technologically more advanced than domestic firms, our findings suggest that diffusion of MNEs' advanced knowledge to potential indigenous entrepreneurs through MNEs' R&D stimulates entry of domestic firms.

Eat, Drink, Firms and Government: An Investigation of Corruption from Entertainment and Travel Costs of Chinese Firms

Entertainment and Travel Costs (ETC) is a standard expenditure item for Chinese firms with an annual amount equal to about 20 percent of total wage bills. We use this objective accounting measure as a basis to analyze the composition of ETC and the effect of ETC on firm performance. We rely on the predictions from a simple but plausible model of managerial decision-making to identify components of ETC by examining how the total ETC responds to different environmental variables. In our empirical analysis we find strong evidence that firms. ETC consists of a mix that includes bribery to government officials both as %u201Cgrease money%u201D and %u201Cprotection money,%u201D expenditures to build relational capital with suppliers and clients, and managerial excesses. ETC overall has a significantly negative effect on firm performance, but its negative effect is much less pronounced for those firms located in cities with low quality government service, those who are subject to severe government expropriation, and those who do not have strong relationship with suppliers and clients. Our findings have important implications on how to effectively curb corruption.

Microinsurance, Trust and Economic Development: Evidence from a Randomized Natural Field Experiment

We report results from a large randomized natural field experiment conducted in southwestern China in the context of insurance for sows. Our study sheds light on two important questions about microinsurance. First, how does access to formal insurance affect farmers' production decisions? Second, what explains the low takeup rate of formal insurance, despite substantial premium subsidy from the government? We find that providing access to formal insurance significantly increases farmers' tendency to raise sows. We argue that this finding also suggests that farmers are not previously insured efficiently through informal mechanisms. We also provide several pieces of evidence suggesting that trust, or lack thereof, for government-sponsored insurance products is a significant barrier for farmers' willingness to participate in the insurance program.Microinsurance; Trust, Natural Field Experiment

China's Land Market Auctions: Evidence of Corruption

This paper studies the urban land market in China in 2003--2007. In China, all urban land is owned by the state. Leasehold use rights for land for (re)development are sold by city governments and are a key source of city revenue. Leasehold sales are viewed as a major venue for corruption, prompting a number of reforms over the years. Reforms now require all leasehold rights be sold at public auction. There are two main types of auction: regular English auction and an unusual type which we call a "two stage auction". The latter type of auction seems more subject to corruption, and to side deals between potential bidders and the auctioneer. Absent corruption, theory suggests that two stage auctions would most likely maximize sales revenue for properties which are likely to have relatively few bidders, or are "cold", which would suggest negative selection on property unobservables into such auctions. However, if such auctions are more corruptible, that could involve positive selection as city officials divert hotter properties to a more corruptible auction form. The paper finds that, overall, sales prices are lower for two stage auctions, and there is strong evidence of positive selection. The price difference is explained primarily by the fact that two stage auctions typically have just one bidder, or no competition despite the vibrant land market in Chinese cities.

Agency problems and commitment in delegated bargaining

In the context of (one-sided) delegated bargaining, we analyze how a principal (a seller) should design the delegation contract in order to provide proper incentives for her delegate (an intermediary) and gain strategic advantage against a third party (a buyer). We consider situations in which there are both moral hazard and adverse selection problems in the delegation relationship and where the seller tries to gain strategic advantage by imposing a minimum price above which she pays the delegate a commission. It is shown that incentives and commitment are substitutes. A low-type agent is given less discretion in dealing with the buyer and weaker incentives, while a high-type agent is given more discretion and stronger incentives.Facultad de Ciencias Económica

Agency Problems and Commitment in Delegated Bargaining

In many economic situations, delegates are hired to play games for their principals. The principal-agent literature focuses on agency problems in the delegation relationships. Following Schelling (1960), the delegation literature emphasizes the commitment effects of delegation contracts against a third party. But not much attention has been paid to the interactions between agency problems and commitment considerations. In the context of one-sided delegated bargaining, we analyze how a principal (a seller) should design the delegation contract in order to provide proper incentives for her delegate (an intermediary) AND gain strategic advantage against a third party (a buyer). We assume that there are both moral hazard and adverse selection problems in the delegation relationship and every player is risk neutral. In the absence of commitment effect, it is shown that a linear contract is optimal. When delegation contracts have commitment value, the seller can gain substantially by committing the delegate to a minimum price, above which she pays the delegate a commission. We show that the seller's strategic manipulation of the delegation contract may cause bargaining failures between the delegate and the buyer when the seller sets a minimum price exceeding some buyers' valuations. Furthermore, the interaction between commitment (through minimum prices) and incentives (measured by commission rates) depends on the nature of the agency problem. When the delegate exerts "bargaining effort" to increase his bargaining power against the buyer, incentives and commitment are substitutes and hence move in opposite directions as the environment changes. When the delegate exerts "marketing effort" to increase the change of finding a buyer, incentives and commitment are neither substitutes nor complements, so can be positively or negatively correlated. We also derive comparative statics of the model. Extensions to multidimensional efforts and unobservable contracts as well as applications to car dealerships are briefly discussed.

Why Do Large Firms Willingly Pay High Wages in Developing Countries?

Using a simple game-theoretical model, this paper provides a new explanation for why large firms in developing economies may willingly pay higher wages than market wage rate. We show that large firms can strategically create entry barriers to the modern sector by setting high wage standards. They may do so to reduce competition or to distort the government's resource allocation. Focusing on the latter case, we also show that the size of the primitive sector will be larger than the efficient level, and public resource allocation will be biased in favor of incumbent large businesses despite the benevolent nature of the government. Using a survey of Chinese industrial firms, we find that industrial concentration is positively correlated with the size-wage effect, and such effect is stronger in less developed provinces. These findings are consistent with our theoretical prediction
