タイトル：Optimal Retirement Policies with Private Annuities
アブストラクト：This paper examines the optimal design of retirement policies that rely on private insurance markets while accounting for financial frictions within these markets. We analyze the impact of uninsurable aggregate interest rate shocks in a life-cycle model where the government screens productivity, longevity, and altruism. We show that observing retirees' annuitization choices helps separate individual types. However, private annuity markets face supply-side inefficiencies due to interest rate risk. To improve market efficiency, the government can issue long-term bonds, supported by interest rate-contingent taxes. Therefore, full privatization can only be optimal without interest rate shocks; otherwise, Social Security remains necessary.

タイトル：Welfare Gains from Product and Process Innovations: The Case of LCD Panels, 2001-2011
アブストラクト：We used unusually detailed data on sales, costs, and investments from the global industry of liquid crystal display (LCD) panels to study the welfare consequences of various types of innovation. Product and process innovations account for 70.6% and 38.9% of total welfare, respectively, with substantial heterogeneity between market segments. The social return on technological investments is unambiguously positive, but the private returns for most firms are negligible because of competition. Simulations suggest the industry-wide incentive to innovate tends to increase with seven-to-six and six-to-five mergers, but the effect becomes mostly negative in subsequent consolidation. We conclude with antitrust policy implications.

タイトル：Parental Paternalism and Patience
アブストラクト:Quantitative evidence on the extent of paternalism within families is scant. We provide a novel measure to study whether and how parents interfere paternalistically in their children's intertemporal decision-making. In an experiment with over 2,000 members from 610 families in Bangladesh, we find that more than half of all parents are willing to pay money to override their children's choices in order to mitigate the (correctly anticipated) level of children's present bias. The extent of parental paternalism is strongly related to parenting styles and we discuss how it interacts with the intergenerational transmission of patience.
