We present a tractable stochastic endogenous growth model that explains how social capital influences economic development. In our model, social capital increases citizens' awareness of government activity. Hence, it alleviates the electoral incentives to under-invest in education, whose returns...

Using a large Australian social survey, combined with precise data on neighbourhood characteristics, I explore the factors that affect trust at a local level (‘localised trust’) and at a national level (‘generalised trust’). Trust is positively associated with the respondent’s...

In markets with imperfect information and heterogeneity, the information technology affects the rate at which agents meet, which in turn affects the distribution of production technologies across firms. We show that in models for such markets there are typically multiple equilibria because...

Payment card associations offer both debit and credit cards and, until recently, engaged in a tie-in on the merchant side through the so-called honour-all-cards (HAC) rule. The HAC rule came under attack on the grounds that the credit and debit card markets are separate markets and that the...

There has been a wide-spread belief that elections with a wide franchise following removal of an oppressive dictator lead to establishment of a government that is not vulnerable to mass protest. At the same time, most of the post-World War II non-constitutional exits of recently-installed...

We examine who benefits when there is a strong leader in place, and those who benefit when a situation lacks a proper leader. There are fractious terrorist groups who seek to serve the same people in a common cause against a common enemy. The groups compete for rents obtained from the public by...

We present a dynamic model of sequential information acquisition by a heterogeneous committee. At each date agents decide whether to vote to adopt one of two alternatives or continue to collect more information. The process stops when a qualified majority vote for an alternative. Three main...

I develop a model of group decision-making, in which a committee generates proposals and holds open discussions, but the ultimate decision is either taken by a leader (decision by authority) or by majority vote. Optimal communication processes are studied that combine both cheap talk statements...

Group liability is often portrayed as the key innovation that led to the explosion of the microcredit movement, which started with the Grameen Bank in the 1970s and continues on today with hundreds of institutions around the world. Group lending claims to improve repayment rates and lower...
