This paper extends Che and Gale (1998) by allowing the incumbent politician to have a preference for the policy position of one of the lobbyists. The effect of a contribution cap is analyzed where two lobbyists contest for ...
In an observational learning environment rational agents may mimic the actions of the predecessors even when their own signal suggests the opposite. In case early movers’ signals happen to be incorrect society may settle ...
We extend the Bikhchandani, Hirshleifer and Welch (1992) informational cascade framework to allow for asymmetric signal accuracy. Simulations demonstrate that even
small departures from symmetry may lead to non-monotonic ...

In synthetic cohort models (cross-sectional data grouped at the cohort and year level), researchers often ignore potential biases induced by sampling error because they have 100 or 200 observations per group. I investigate ...
This paper investigates the link between nationality of ownership and wage elasticities of labour demand at the level of the plant. In particular, we examine whether labour demand in multinationals becomes less elastic ...
There is a well-established debate between Heckman sample selection and two-part models in health econometrics, particularly when no obvious exclusion restrictions are available. Most of this debate has focussed on the ...

Grouping models are widely used in economics but are subject to finite sample bias. I show that the standard errors-in-variables estimator (EVE) is exactly equivalent to the Jackknife Instrumental Variables Estimator (JIVE), ...
This paper proposes a new method of measuring obesity using Body Mass Index (BMI) data. Conventional measures which simply count the number of individuals with BMI in excess of an upper limit ignore the extent by which ...
Individuals who vote in one election are also more likely to vote in the next. Modelling the causal relationship between past and current voting decisions however is intrinsically difficult, as this positive association ...
