摘要：In this rejoinder, we address the concern about equilibrium existence in our previous work published in 2013. By making the simple adjustment of discretizing inventory ordering amounts to prevent inventory orders in arbitrarily small increments, we show that the results from that paper hold, thus maintaining the robustness of the insights obtained.

摘要：This paper examines the role of advice in early firm development and growth, drawing on detailed data from a global program where angel investors and venture capitalists (VCs) mentored founders over several months. Leveraging variation in mentors' availability to support start-ups because of personal scheduling conflicts, I find that advice significantly improves start-ups' future market performance. To explore how advice shapes early firm development, I develop a novel typology of start-up ac...

摘要：Most school choice matching mechanisms employed in theory and practice assume that schools rank students by characteristics that cannot be manipulated. However, parents may have incentives to misstate information used for determining school priorities, such as the proximity of the residential address to a school, particularly when such misrepresentations are difficult to detect or carry minimal penalties. If manipulation of school priorities occurs, the efficiency and fairness of the matching ...

摘要：Do dealers use their financing discretion to charge higher interest rate markups to high-risk customers? We use unique transaction-level data to examine finance and vehicle profits in the subprime auto market with three main results. First, financing subprime customers is costly for dealerships because of loan discounts that are only partially offset by proceeds from interest rate markups. Second, financing is costliest to dealers for deep subprime customers with low credit scores and low inco...

摘要：This paper addresses an important class of restless multiarmed bandit (RMAB) problems that finds broad application in operations research, stochastic optimization, and reinforcement learning. There are N independent Markov processes that may be operated, observed and offer rewards. Due to the resource constraint, we can only choose a subset of M (M < N) processes to operate and accrue reward determined by the states of selected processes. We formulate the problem as a partially observable RMAB...
