Household responsibility system and China's agricultural Growth revisited: Addressing endogenous institutional change

The rise of the Household Responsibility System has been widely viewed as a significant contribution to China's agricultural growth. However, this empirical conclusion is rested upon a convenient but doubtful presumption that the process of institutional change, also known as decollectivization, is exogenous. We contribute to this literature by explicitly recognizing the endogeneity of institutional changes, and exploit exogenous variations in lagged weather shocks and initial fixed assets for consistent estimation. With improved data on irrigation, mechanization, weather and institutional changes in a provincial panel data during 1970–1987, the results of panel instrumental estimations reveal that the Household Responsibility System had a significantly positive effect on China's agricultural growth, which was larger than indicated by OLS estimates that suffer from adverse selection and attenuation biases.     

Cost-sharing in directed networks: Experimental study of equilibrium choice and system dynamics

This study reports the results of an experiment on directed networks with positive externalities induced by cost-sharing. Subjects participated in a network game in which they had to choose between private and public transportations. If a player chose public transportation, then she shared the travel cost equally with other players making the same choice, whereas if she chose private transportation, then her travel cost was fixed. Travel costs on the private route were manipulated across the two experimental conditions. In one condition, these costs were homogeneous among players; in the other condition, they were heterogeneous among players and only privately known. We found that half (none) of the player groups in the homogeneous (heterogeneous) condition converged toward the efficient equilibrium. Examination of the system dynamics shows that convergence toward efficiency was facilitated by: (1) the existence of an intermediate equilibrium choice; and (2) strategic teaching by which a farsighted player chooses strategies with poor short-term payoff in order to shift group decisions to the efficient equilibrium and thereby increase her own long-term benefit.     

On post-IPO stock price performance: A comparative analysis of RLBOs and IPOs

This is the first study to examine the post-IPO stock price performance by differentiating between IPOs and three types of RLBOs (i.e. public-to-private (or re-IPOs), division-to-private, and private-to-private deals). We document that public-to-private RLBOs outperform their industry rivals, IPOs, mature firms in comparable industries, and a propensity-score matched control group for up to five years post-offering. Further, we document that, within RLBOs, public-to-private RLBOs, outperform private-to-private and division-to-private RLBOs. We also find support for the underwriter signaling effect for public-to-private RLBOs. Our analysis identifies for the first time what private period restructuring activities contribute to superior post-re-IPO stock price performance. Further, the beneficial effects of private period restructurings are enhanced for deals associated with prestigious underwriters. Our findings suggest that first IPOs and re-IPOs differ substantially in term of post-offer performance, the impact of prestigious underwriters on performance, and performance over time.     

Judgment aggregation in search for the truth

We analyze the problem of aggregating judgments over multiple issues from the perspective of whether aggregate judgments manage to efficiently use all voters' private information. While new in judgment aggregation theory, this perspective is familiar in a different body of literature about voting between two alternatives where voters' disagreements stem from conflicts of information rather than of interest. Combining the two bodies of literature, we consider a simple judgment aggregation problem and model the private information underlying voters' judgments. Assuming that voters share a preference for true collective judgments, we analyze the resulting strategic incentives and determine which voting rules efficiently use all private information. We find that in certain, but not all cases a quota rule should be used, which decides on each issue according to whether the proportion of ‘yes’ votes exceeds a particular quota.

Auction fever: Rising revenue in second-price auction formats

The prevalent term “auction fever” visualizes that ascending auctions – inconsistent with theory – are likely to provoke higher bids than one-shot auctions. To explore and isolate causes of auction fever experimentally, we design four different strategy-proof auction formats and order these according to expected rising bids based on pseudo-endowment effect arguments (psychological ownership and disparity between willingness to pay and willingness to accept). Observed revenues in the experiment in the four formats rank as expected if bidders have private uncertain values (the private information of a bidder is the distribution of her value). A control treatment supports our view that the traditional private certain values approach prevents auction fever in the laboratory. Another control treatment with a procurement auction relates the auction fever bids to bids in a one-shot auction with real endowments. We conclude that, when bidders are uncertain about their valuations, auctions that foster pseudo-endowment may raise bids and revenues.

The impact of IT-enabled customer service systems on service personalization,customer service perceptions,and hotel performance

Customer service is a critical element of a hotel's strategy and an important lever for differentiation of the hotel's offer. Over the last two decades, information systems have contributed to the transformation of customer interactions, enabling an unprecedented scale and scope of service personalization in the tourism industry. This paper reports the results of a mixed method study in a hotel that offers three contributions to the development and refinement of IT-enabled service personalization theory. It explores the role of signifiers in the design of customer service systems, showing that they significantly increase customer preference elicitation during the learning phase of the service personalization process. It then demonstrates that improved preference elicitation translates into higher customer service evaluations and value perceptions of the hotel. Finally, our study shows that IT-enabled service personalization creates financial benefits for the hotel via revenue share-shift from costly intermediated to direct distribution channels.     

Bribery,corruption and bureaucratic hassle: Evidence from Myanmar

Corruption has been found to be the most severe obstacle to business operations, according to a recent survey of over 3000 firms in Myanmar. This paper sets out to understand the structure of corruption through an econometric analysis of this survey. It finds that firms with higher ‘ability to pay’ (proxied by sales revenue and employee growth) are more likely to pay bribes. While firms with lower ‘refusal power’ (i.e. those dependent on bureaucratic permissions to export and import) are more likely to find corruption to be an obstacle. A distinct but related question is whether bribes act as ‘efficiency grease’ by allowing firms to circumvent red tape. No evidence is found to support this hypothesis; in fact, firms that pay bribes report greater bureaucratic hassle compared to firms that do not. This result fits in more closely with the view that red tape could be used to extract bribes from firms.
