False prosperity: Rethinking government support for farmers’ cooperatives in China

The rapid development of farmers’ cooperatives in rural China cannot be separated from government support. To ensure the growth of farmers’ cooperatives, the Chinese government uses it as a key performance indicator for its local institutions. Superficially, rural China's cooperative population and membership size witnessed rapid growth during the first decade after the Farmers’ Specialized Cooperatives Law was enacted in 2007; however, such government intervention also leads to non-standard phenomena due to market distortion. Using nationally representative survey data from 504 cooperatives in Jiangsu, Jilin, and Sichuan provinces, this paper provides a reliable estimate of the “shell cooperative” rate around 2014. The empirical study sheds further light on the role of government during the period of rapid but chaotic growth by a subset containing 241 marketing cooperatives. Results show that direct administrative intervention leads to the emergence of many shell cooperatives (approximately 37%). Further study also confirms that task-oriented policy support is only positively associated with the nominal coverage ratio but has no significant relationship with cooperatives’ function. This study provides new insights into the formation of shell cooperatives and suggests that direct administrative intervention may not be a good strategy for promoting the sustainable development of farmers’ cooperatives.     

Stackelberg equilibrium with many leaders and followers. The case of zero fixed costs

I study a version of the Stackelberg game with many identical firms in which leaders and followers use a continuous cost function with no fixed cost. Using lattice theoretical methods I provide a set of conditions that guarantee that the game has an equilibrium in pure strategies. With convex costs the model shows the same properties as a quasi-competitive Cournot model. The same happens with concave costs, but only when the number of followers is small. When this number is large the leaders preempt entry. I study the comparative statics and the limit behavior of the equilibrium and I show how the main determinants of market structure interact. More competition between the leaders always displaces the followers. Instead, how a stronger threat of entry affects the equilibrium depends on the technology. With strictly convex costs it is the followers that eventually displace the leaders.     

Second chance offers versus sequential auctions: theory and behavior

Second chance offers in online marketplaces involve a seller conducting an auction for a single object and then using information from the auction to offer a losing bidder a take-it-or-leave-it price for another unit. We theoretically and experimentally investigate this practice and compare it to two sequential auctions. We show that the equilibrium bidding strategy in the second chance offer mechanism only exists in mixed strategies, and we observe that this mechanism generates more profit for the auctioneer than two sequential auctions. We also observe virtually no rejections of profitable offers in the ultimatum bargaining stage.

Recurrent crises in global games

Global games have unique equilibria in which aggregate behavior changes sharply when an underlying random fundamental crosses some threshold. This property relies on the existence of dominance regions: all players have a highest and lowest action that, for some fundamentals, is strictly dominant. But if the fundamental follows a random walk, it eventually spends nearly all of its time in these regions: crises gradually disappear. We obtain recurring crises by adding a single large player who lacks dominance regions. We also show that in order to obtain recurring crises, one must either relax dominance regions or restrict to fundamentals that continually return to or cross over a fixed region.
