We model unobserved preference heterogeneity in demand systems as random Barten scales in utility functions. These Barten scales appear as random coefficients multiplying prices in demand functions. Consumer demands are nonlinear in prices and may have unknown functional structure. We therefore prove identification of additive Generalized Random Coefficients models, defined as additive nonparam...

A quasi-line graph is a graph in which the neighbourhood of any vertex can be covered by two cliques; every line graph is a quasi-line graph. Reed conjectured that for any graph G, χ(G) ≤ d12(∆(G) + 1 + ω(G))e [13]. We prove that the conjecture holds if G is a quasi-line graph, extending a result of King, Reed and Vetta, who proved the conjecture for line graphs [8], and improving the bound of ...

Imperfect information and inattention to energy costs are important potential motivations for energy efficiency standards and subsidies. We evaluate these motivations in the lightbulb market using a theoretical model and two randomized experiments. We derive welfare effects as functions of reduced-form sufficient statistics capturing economic and psychological parameters, which we estimate usin...

The paper reports the result of an experimental game on asset integration and risk taking. We find some evidence that winnings in earlier rounds affect risk taking in subsequent rounds, but no evidence that real life wealth outside the experiment affects risk taking. Controlling for past winnings, participants receiving a low endowment in a round engage in more risk taking. We test a ‘keeping-u...

Micro-entrepreneurs often lack the financial literacy required for the complex financial decisions they face. We conduct a randomized control trial with a bank in the Dominican Republic to compare the impact of two distinct programs: a standard accounting training versus a simplified, rule-of-thumb training that teaches basic financial heuristics. Only the latter produced significant improvemen...

The binary diffusion coefficients of ferrocene and 1,1’-dimethylferrocene at infinite dilution in supercritical carbon dioxide, D12, were measured by the chromatographic impulse response (CIR) method at temperatures from 308.2 to 323.2 K and pressures from 9 to 40 MPa. The D12 data for ferrocene were also measured by the Taylor dispersion method. The diffusion data of ferrocene measured by the ...

The Effect of Power Outages and Cheap Talk on Willingness to Pay to Reduce Outages Using an open-ended contingent valuation survey, we analyze how (i) experience of a power outage due to one of the worst storms ever to hit Sweden and (ii) a cheap talk script affect respondents’ WTP to avoid power outages. Experience significantly increases and a cheap talk script decreases the proportion of res...

This paper provides an empirical analysis of the effects of weight-based pricing in the collection of household waste. Using a comprehensive panel data set on all households in a Dutch municipality we estimate short-run as well as long-run price effects for the amounts of both compostable and non-recyclable household waste. We find significant and sizeable price effects, with the elasticity for...

The Measurement of Child Costs: Evidence from Ireland We apply an extension of the Rothbarth approach to estimate the share of household resources accruing to children (i.e., the cost of children) in Ireland. The method also allows us to identify the economies of scale in the household and indifference scales in Lewbel (2003)’s sense. A practical aspect of the present approach is that it does n...

Household accumulation of debt and arrears on debt, especially among low income families, is an extremely topical issue in the UK media and in policy circles. The paper utilises data from the UK’s Survey of Low Income Families in order to examine use of credit, and default and arrears, among low income families with children. It shows how credit use and accumulation of arrears differs between s...
