This paper proposes a method for the welfare analysis of pay-as-you-go social security systems. We derive a formula for the welfare consequences of a permanent marginal change in the payroll tax rate that is valid under weak assumptions about the deep structure of the economy. Our approach...

In an environment that features second-degree price discrimination, this paper fully characterizes the set of surplus divisions that can arise from all possible information consumers have about their valuation. By extending the techniques developed in a companion paper (Yang, 2019a), I show that...

This paper studies consumers' incentives to hide their purchase histories when the seller's prices depend on previous behavior. Through distinct channels, hiding both hinders and facilitates trade. Indeed, the social optimum involves hiding to some extent, yet not fully. Two opposing effects...

This paper uses a simple diagram to compare two pricing strategies: price-quantity packages, and a two-part tariff from the monopoly and from the welfare points of view. It is shown that in the two-type consumer case when the monopoly is concerned, the price-quantity packages strategy dominates...

This Article critique the role that the partial equilibrium trade-off paradigm plays in the debate over the definition of “consumer welfare” that courts should employ when developing and applying antitrust doctrine. The paper contends that common reliance on the paradigm distorts the debate...

We develop an endogenous growth model to quantify how permanent structural policy changes that enhance the fiscal policy mix, markets' functioning, and public institutions' quality affect long-term growth and welfare. The reforms include increased public investment, reduced market power through...

In their quest to maximize efficiency, law and economics scholars often produce novel, creative, and counterintuitive legal rules. Indeed, legal economists have argued for baby selling, against anti-discrimination laws in the workplace, and for insider trading. In this essay, we discuss some...

The paper explores the hypothesis of a double dividend from environmental taxation i.e. whether shifting the burden of taxation away from labour toward the environment can boost employment and increase welfare. We present a general-equilibrium model where the economy is distorted by labour...
