    Earn More Tomorrow: Overconfidence, Income Expectations and Consumer Indebtedness

    This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt-taking. We show suggestive evidence for a link between overconfidence and borrowing behavior in a representative survey of German households (GSOEP-IS). This motivates a laboratory experiment to study causality behind these effects. In two experiments, participants can purchase goods by borrowing ...

    Sin Taxes and Self-Control

    According to theory, "sin taxes" are welfare improving if consumers with low self-control respond at least as much to the tax as consumers with high self-control. We investigate empirically if demand response to soft drink and fat tax variations in Denmark depends on consumers' self-control. We use a unique home-scan panel that includes a survey measure of self-control. When taxes increase, consumers ...

    Agents, Landlords and Tenants: Price Regulation in a Thick Two-sided Market

    This paper examines the impacts of new policies aimed at reducing the cost of renting by regulating the actions of intermediaries in the rental market. We highlight how information frictions between buyers and intermediaries can give rise to rents in the thick two-sided market. The distribution of these rents between intermediaries and sellers, as well as the impact of price regulation, depends on...

    How Divestitures Affect Bargaining Power

    This paper studies how bargaining power is affected by merger and divestiture policies. I provide a new empirical framework to compute bounds on brand-level bargaining weights using widely available sales data. Next, I exploit the variation in brand ownership caused by a large merger, cleared conditional on divestiture, in the U.S. deodorant market, to quantify the extent to which divestitures...

    Hours Risk and Wage Risk: Repercussions over the Life Cycle

    We decompose earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks, we formulate a life-cycle model of consumption and labor supply. For estimation, we use data on married American men from the Panel Study of Income Dynamics. Permanent wage shocks explain ...

    Quantifying Bargaining Power in Supply Chains: Essential for Merger Control

    Merger control plays a central role in competition policy. When assessing proposed mergers, Competition Authorities should consider its impact on all relevant markets. Large mergers between manufacturers typically impact competition, thus requiring the approval of Competition Authorities. Divestitures are often a condition of merger approval. This report investigates the effectiveness of implementing ...
