The chocolate supply chain exemplifies the social and environmental challenges within global food systems. Growing awareness of environmental impact and ethical production practices is increasingly shaping consumer choices and influencing food policy. This highlights the need for an integrated...

Response times contain information about economically relevant but unobserved variables like willingness to pay, preference intensity, quality, or happiness. We provide a general characterization of the properties of latent variables that can be detected using response time data. Our theoretical...

We study how individuals in six Latin American countries value public versus private provision of education and healthcare using a survey experiment. Respondents were randomly assigned to vignettes that vary income, service quality, and provider type. Perceived quality is the main driver of...

Revealed preference theory (RPT) and its behavioral extension (BRPT) underpin an important strand of welfare economics. Their normative appeal rests on the claim that welfare can be inferred from observed behavior without substantive assumptions about what agents should value - a property I call...

The objective of the research is to examine the effects of product attributes on consumers' willingness to pay (WTP) for organic oranges in the Mekong Delta and estimate the consumers' WTP for each attribute. The study used survey data from 413 households in the Mekong Delta from March 2022 to...

Frame of the research. Modal choice in urban and inter-urban mobility holds a significant potential impact on sustainable well-being across multiple dimensions (e.g. environmental impact, health, social equity). The reliance on private modes of transport has been associated with negative effects...

Corporate social responsibility and the private provision of (global) public goods are of key interest to economists and policymakers. Over the last few years, many more private companies made their operations carbon neutral. It is an empirical question how consumers value carbon-neutral and...

According to a widely shared view, the development of demand theory in the first half of the twentieth century was heavily influenced by the anti-psychological attitudes of economists. I call this view 'anti-psychologist thesis,' and I criticize it on several grounds. I propose an alternative...

Welfare economics relies on access to agents' utility functions: we revisit classical questions in welfare economics, assuming access to data on agents' past choices instead of their utilities. Our main result considers the existence of utilities that render a given allocation Pareto optimal. We...

This paper examines consumers' intended adoption of a digital euro in Austria using a discrete choice experiment. We estimate a mixed logit model to quantify the role of key attributes such as privacy, offline functionality, security against financial loss, monetary incentives, and payment form...

Randomized controlled trials remain underutilized in informing policy design, despite their potential. Moral objections to experimentation ("experiment aversion") have been proposed as an explanation. We present three studies with members of the general public and policy-makers that allow us to...

I analyze Dutch survey data that contains rich information on political preferences, personality traits, and socioeconomic background. I show that voting and political opinions are better predicted by personality and economic preferences than by a rich set of socioeconomic characteristics....

The ability of countries in Latin America to achieve net zero greenhouse gas (GHG) emissions by mid-century, the target set by the Paris Agreement, will depend critically on citizen support. To gauge this support, we administered a contingent valuation survey to representative samples in seven...

With the growing adoption of electric vehicles, understanding user charging behavior is increasingly important for informing operational, investment, and policy decisions regarding their integration into the power system. While utility functions are commonly used to describe user preferences in...

This paper examines preferences for gender diversity among co-workers. Using stated-choice experiments with 5,400 PhD students and university students in Germany, we uncover a substantial willingness to pay (WTP) for gender diversity of up to 5% of earnings on average. Importantly, we find that...

Inspired by the controversial public and political debate in the European Union (EU) about legal initiatives to protect human rights and the environment along supply chains (e.g., the Corporate Sustainability Due Diligence Directive, CSDDD), this paper examines individual preferences for...

This paper examines preferences for gender diversity among co-workers. Using stated-choice experiments with 5,400 PhD students and university students in Germany, we uncover a substantial willingness to pay (WTP) for gender diversity of up to 5% of earnings on average. Importantly, we find that...
