Intermediation in Networks
I study intermediation in networked markets using a stochastic model of multilateral bargaining in which players compete on different routes through the network. I characterize stationary equilibrium payoffs as the fixed point of a set of intuitive value function equations and study efficiency and the impact of network structure on payoffs. There is never too little trade but there may be an inefficiency through too much trade in states where delay would be efficient. With homogeneous trade surplus the payoffs for players that are not essential to a trade opportunity go to zero as trade ...

Assessing Contagion Risk in a Financial Network
Since the 2008 financial crisis, there has been an explosion of research trying to understand and quantify the default spillovers that can arise through counterparty risk. This first of two posts delves into the analysis of financial network contagion through this spillover channel. The authors introduce a framework, originally developed by Eisenberg and Noe, that is useful for thinking about default cascades.

Filling in the Blanks: Network Structure and Interbank Contagion
The network pattern of financial linkages is important in many areas of banking and finance. Yet bilateral linkages are often unobserved, and maximum entropy serves as the leading method for estimating counterparty exposures. This paper proposes an efficient alternative that combines information-theoretic arguments with economic incentives to produce more realistic interbank networks that preserve important characteristics of the original interbank market. The method loads the most probable links with the largest exposures consistent with the total lending and borrowing of each bank, yielding ...

The Role of Interbank Relationships and Liquidity Needs
In this paper, we focus on the interconnectedness of banks and the price they pay for liquidity. We assess how the concentration of credit relationships and the position of a bank in the network topology of the system influence the bank?s ability to meet its liquidity demand. We use quarterly data of bilateral interbank credit exposures between all German banks from 2000 to 2008 to measure interbank relationships and the network characteristics. We match these data with the bids placed by the individual banks in the European Central Bank?s (ECB) weekly repo auctions. The bids measure each ...

Identifying Contagion in a Banking Network
We present the first micro-level evidence of the transmission of shocks through financial networks. Using the network of credit default swap (CDS) transactions between banks, we identify bank CDS returns attributable to counterparty losses. A bank's own CDS spread increases whenever counterparties from whom it has purchased default protection themselves experience losses. We find no such effect from losses of non-counterparties, nor from counterparties to whom the bank has sold protection. The effect on bank CDS returns through this counterparty loss channel is large relative to the direct ...

Value Added and Productivity Linkages Across Countries
What is the relationship between international trade and business cycle synchronization? Using data from 40 countries, we find that GDP comovement is significantly associated with trade in intermediate inputs but not with trade in final goods. Motivated by this new fact, we build a model of international trade that is able to replicate the empirical trade-comovement slope, offering the first quantitative solution for the Trade Comovement Puzzle. The model relies on (i) global value chains, (ii) price distortions due to monopolistic competition and (iii) fluctuations in the mass of firms ...

Efficient Public Good Provision in Networks : Revisiting the Lindahl Solution
The provision of public goods in developing countries is a central challenge. This paper studies a model where each agent?s effort provides heterogeneous benefits to the others, inducing a network of opportunities for favor-trading. We focus on a classical efficient benchmark ? the Lindahl solution ? that can be derived from a bargaining game. Does the optimistic assumption that agents use an efficient mechanism (rather than succumbing to the tragedy of the commons) imply incentives for efficient investment in the technology that is used to produce the public goods? To show that the answer is ...

How Large are Default Spillovers in the U.S. Financial System?
When a financial firm defaults on its counterparties, the counterparties may in turn become unable to pay their own creditors, and so on. This domino effect can quickly propagate through the financial system, creating undesirable spillovers and unnecessary defaults. In this post, the authors use the framework discussed in the first post of this two-part series to answer the question: How vulnerable is the U.S. financial system to default spillovers?

Community Leaders and the Preservation of Cultural Traits
We explain persistent differences in cultural traits of immigrant groups with the presence of community leaders. Leaders influence the cultural traits of their community, which have an impact on the group?s earnings. They determine whether a community will be more assimilated and wealthier or less assimilated and poorer. With a leader, cultural integration remains incomplete. The leader chooses more distinctive cultural traits in high-productivity environments and if the community is more connected. Lump-sum transfers to immigrants can hinder cultural integration. These findings are in line ...

Do informal referrals lead to better matches? Evidence from a firm's employee referral system
The limited nature of data on employment referrals in large business and household surveys has so far limited our understanding of the relationships among employment referrals, match quality, wage trajectories, and turnover. Using a new, firm-level data set that includes explicit information on whether a worker was referred by a current employee of the company, we are able to provide rich detail on these empirical relationships for a single U.S. corporation, and to test various predictions of theoretical models of labor market referrals. Predictions with which our results align include: 1) ...
