摘要：We show how manufacturers can benefit from contracts that incentivize retailers to purchase multiple products from the same manufacturer. We isolate two effects: first, under standard contractual inefficiencies, which give rise to double marginalization, such contracts can increase channel profits (the improved contractual efficiency effect); second, when a weaker product is tied to a particularly strong must-stock product, such contracts can also reduce a retailer's position and shift rent to...

摘要：On-demand ride-sharing aims to fulfill riders' transportation needs whenever and wherever they want. Although this service level appeals to riders, overall system efficiency can improve substantially if riders are willing to be flexible. Here, we explore riders' flexibility in space via walking to more accessible pickup locations. Ride-sharing platforms have traditionally implemented dynamic walking to optimize rider pickup locations and rider-driver assignment jointly. We propose an alternati...

摘要：Although investor attention is fundamental to the efficient functioning of capital markets, it is also an elusive construct that researchers struggle to measure. In recent years, the search volume index (SVI) of ticker searches on Google has become a ubiquitous measure of investor attention, but the amount and effects of measurement error in ticker SVI are unknown. We investigate measurement error in ticker SVI using a data set of 2.7 billion website visits following Standard and Poor's 500 fi...

摘要：Quality internet access is critical to participating in contemporary society. Unfortunately, many households-particularly those of low socioeconomic status and/or those in rural areas-do not have quality internet access. Some have no access, whereas others are reliant on their mobile data plans for internet access (i.e., they are smartphone dependent). This generates inequality in internet access and use. Given the smartphone dependence of many disadvantaged households, we explore whether impr...

摘要：We study the stochastic multi-armed bandit problem and design new policies that enjoy both optimal regret expectation and light-tailed risk for regret distribution. We first find that any policy that obtains the optimal instance-dependent expected regret could incur a heavy-tailed regret tail risk that decays slowly with T. We then focus on policies that achieve optimal worst-case expected regret. We design a novel policy that (i) enjoys the worst-case optimality for regret expectation and (ii...

摘要：Stochastic gradient descent (SGD) has proven effective in solving many inventory control problems with demand learning. However, it often faces the pitfall of an infeasible target inventory level that is lower than the current inventory level. Several recent works have been successful in resolving this issue in various inventory systems. However, their techniques are rather sophisticated and difficult to apply to more complicated scenarios, such as multiproduct and multiconstraint inventory sy...

摘要：On decentralized e-commerce platforms, search algorithms play a critical role in matching buyers and sellers. A typical search algorithm routinely refines and improves its catalog of data to increase search precision, but the effects of a more precise search are little known. We evaluate such effects via a 2019 quasiexperiment on a world-leading e-commerce platform in which the search algorithm refined some product categories into finer subgroups to allocate consumer queries to more relevant p...

摘要：We study platform financing in comparison with trade credit for lending to third-party sellers, considering scenarios where default risk is driven by external factors (exogenous) or influenced by the parties' decisions (endogenous). Our findings indicate that under exogenous default risk, although platform financing exposes the platform to the seller's default risk, it can enhance the seller's sales by providing low-rate finance and reducing the wholesale price because the supplier remains iso...

摘要：Most research on systemic stability assumes an economy where banks are subject to exogenous shocks. However, in practice, banks choose their exposure to risk. I show that there exists a network risk-taking externality: the risk exposure choices made by connected banks are strategically complementary. Banks within financial networks, especially densely connected ones, become endogenously exposed to excessive risks. The theory offers several novel perspectives on policy debates. For instance, it...
