This paper deals with trade platforms whose operators not only allow third party sellers to offer their products to consumers, but also offer products themselves. In this context, the platform operator faces a hold-up problem if he uses classical twopart tariffs only as potential competition...

This paper explores the relationship between market accessibility and various participants' welfare in an intermediated directed-search market. For a general class of meeting technologies, we provide a necessary and sufficient condition under which efficiency requires imperfect accessibility,...

In intermediated markets, trading takes time and intermediaries extract rents. We estimate a structural search‑and‑bargaining model to quantify these trading delays, intermediaries’ ability to extract rents, and the resulting welfare losses in government and corporate bond markets. Using...

Intermediaries in decentralized markets can affect buyer welfare both directly, by reducing expenses for buyers with high search cost and indirectly, through a search-externality that affects the prices paid by buyers that do not use intermediaries. I investigate the magnitude of these effects...

I develop a theory of intermediation in a market where agents meet bilaterally to trade and buyers cannot commit to payments. Some agents observe the past trading history of traders in the market. These informed agents can secure trades by punishing traders who previously defaulted. The...

We derive closed-form strategies for a broker who provides liquidity to an informed trader and to a noise trader over a finite-time and infinite-time trading horizon. The flow of the noise trader is uninformative and the broker trades with the noise trader at a profit, on average. On the other...

This study examines whether and how brokers manage the distribution of their stock recommendations. We document that in a quarter if a broker’s percentage of buy recommendations in the first two months is substantially higher than the historical average, the broker issues significantly fewer...

We examine whether brokers in order-driven markets possess an information advantage over their customers. We compare the price impact of proprietary trades to customer trades in Borsa Istanbul. We find an asymmetric effect: While proprietary buy trades lead to a significant price response...

We study the effect on economic outcomes resulting from reputation in a market and related locational advantage of intermediaries through the lens of brokered transactions in the commercial real estate market. Specifically, we explore how the locational advantage generated by a reputation for...

On the online content market, platforms are both “the matchmakers and the taste-makers”: the content that attracts the highest amount of consumers is promoted - namely through algorithmic recommender systems -, attracting even more consumers and drawing in even more creators of this...

After 10 years analysing the patent market, we have some very direct advice this year. If you are in-house counsel, to borrow a line from Samuel L Jackson: “Hold onto your butts.” These next few years are going to be tough. If you have not already signed up with a defensive aggregator such...

We argue that the emergence of a well-developed market for patented technologies over the late nineteenth and early twentieth centuries facilitated the emergence of a group of highly specialized and productive inventors by making it possible for them to transfer to others responsibility for...

This paper examines the relationship between broker network connectivity and stock returns in an order-driven market. Considering all stocks traded in Borsa Istanbul between January 2006 and November 2015, we estimate the monthly density, reciprocity and average weighted clustering coefficient...

We study a home rental market where hosts compete in prices and decide which guests to accept. Such screening results in inefficiently many rejections and can reduce welfare. In a unique symmetric equilibrium, hosts randomize over prices so that it may be unprofitable for them to accept some...

Active markets for intellectual property (IP) are desirable because they facilitate the reallocation of new inventions to those who can best commercialize them. Therefore, active IP markets provide an incentive for inventors and specialized startups to invent in the first place, which promotes...

This paper analyzes how the competition among real estate brokers impacts housing prices in a typical sellers’ market in China. In a theoretical model, we discover a broker competition mechanism in which brokers compete for listings by promising higher transaction prices and compete for buyers...

Despite the popular emergence of online property brokerage platforms in the second-hand housing market, little is known about whether and how these platforms would influence the market, especially in terms of housing price. We thus assemble and analyze data from multiple sources about the entry...

I study broker intermediation in entrepreneurial financing. Brokers intermediate 15% of startup offerings, but 20% of these brokers are unregistered "finders." Issuers using finders are 30% and 20% less likely to have successful post-funding outcomes than issuers in registered-broker and direct...

This research provides evidence on the role of information asymmetry and personal affiliations in housing transactions using a novel dataset that allows observation of detailed information about the property, broker, and seller. Sellers holding a real estate license are found to obtain about 1.6...
