While interest in social determinants of individual behavior has led to a rich theoretical literature and many efforts to measure these influences, a mature "social econometrics" has yet to emerge. This chapter provides a critical overview of the identification of social interactions. We...

While interest in social determinants of individual behavior has led to a rich theoretical literature and many efforts to measure these influences, a mature social econometrics has yet to emerge. This chapter provides a critical overview of the identification of social interactions. We consider...

This paper provides a systematic analysis of identification in linear social interactions models. This is both a theoretical and an econometric exercise as the analysis is linked to a rigorously delineated model of interdependent decisions. We develop an incomplete information game that...

Poverty trap models are dynamical systems with more than one attractor. Similar dynamical systems arise in optimal growth and macroeconomic models. These systems are often studied empirically by ad hoc methods relying on intuition from deterministic systems, such as looking for multiple peaks in...

Although the Russian economy performed poorly in the first seven years following the collapse of the USSR, the reforms of the 1990s laid the foundation for strong growth in 1998–2008. The early 2000s also saw successful reforms, such as the flat income tax and streamlined regulations....

Randomised controlled trials (RCTs) are a major source of individual patient level data (IPD) on the clinical outcomes, costs and other measures of health consequences associated with alternative healthcare interventions. These data are typically used to establish the ‘value for...

There is disagreement about whether large and complex financial institutions should be allowed to use US bankruptcy law to reorganise when they get into financial difficulty. We look at the events surrounding the Lehman Brothers bankruptcy filing for lessons as to whether bankruptcy law could be...

Lloyd Shapley is considered one of the pioneers of game theory. His most prominent contributions are the inception and study of value theory and core theory. These two theories are the key to solving problems involving the allocation of goods or payoffs achievable through cooperation....

After rapidly cutting short-term interest rates to their effective lower bounds during the financial crisis of 2008–09, central banks in the USA and UK turned to quantitative easing (QE) in order to sustain aggregate demand and avoid a Japanese style deflationary spiral. The European...

Following the Internet’s widespread adoption, much economic work has studied ‘online platforms’: firms that mainly interact with consumers in cyberspace. This article surveys such work, focusing on the ways in which traditional economic models have been adapted to incorporate...
