Estimating Causal Peer Influence in Homophilous Social Networks by Inferring Latent Locations.
By: Edward McFowland III and Cosma Rohilla Shalizi
Social influence cannot be identified from purely observational data on social networks, because such influence is generically confounded with latent homophily, that is, with a node’s network partners being informative about the node’s attributes and therefore its... View Details

Why Doesn't Capitalism Flow to Poor Countries?
By: Rafael Di Tella and Robert MacCulloch

Party-State Capitalism in China
By: Margaret Pearson, Meg Rithmire and Kellee Tsai
The “state capitalism” model, in which the state retains a dominant role as owner or investor-shareholder amidst the presence of markets and private firms, has received increasing attention, with China cited as the main exemplar. Yet as models evolve, so has China’s... View Details

By: Thalia Wheatley, Anna Weinberg, Christine E. Looser, Tim Moran and Greg Hajcak
Faces are visual objects that hold special significance as the icons of other minds. Previous researchers using event-related potentials (ERPs) have found that faces are uniquely associated with an increased N170/vertex positive potential (VPP) and a more sustained... View Details

Market Liquidity as a Sentiment Indicator
By: Malcolm Baker and Jeremy Stein
We build a model that helps to explain why increases in liquidity-such as lower bid-ask spreads, a lower price impact of trade, or higher turnover-predict lower subsequent returns in both firm-level and aggregate data. The model features a class of irrational... View Details

Dynamic Pricing, Intertemporal Spillovers, and Efficiency
By: Alexander J. MacKay, Dennis Svartbäck and Anders G. Ekholm
Pricing technology that allows firms to rapidly adjust prices has two potential benefits.
Time-varying prices can respond to high-frequency demand shocks to generate greater revenues,
and they can also be used to smooth out demand to reduce costs. Using data... View Details

Behavioral Hazard in Health Insurance
By: Katherine Baicker, Sendhil Mullainathan and Joshua Schwartzstein
A fundamental implication of standard moral hazard models is overuse of low-value medical care because copays are lower than costs. In these models, the demand curve alone can be used to make welfare statements, a fact relied on by much empirical work. There is ample... View Details
