Prices vs. Quantities and the Intertemporal Dynamics of the Climate Rent

This paper provides a formal survey of price and quantity instruments for mitigating global warming. We explicitly consider policies’ impact on the incentives of resource owners who maximize their profits intertemporally. We focus on the informational and commitment requirements of the regulator. Furthermore, we study the interplay between (private) resource extraction rent and (public) climate rent and ask how property and management of the climate rent can be assigned between regulator and resource sector. There are only two instruments that unburden the regulator from the complex intertemporal management of the climate rent and associated commitment problems: in the cost-benefit world, we derive a stock-dependent tax rule; in the cost-effective (carbon budget) world, only an emissions trading scheme with free banking and borrowing can shift intertemporal timing decisions completely to the market.resource extraction, climate rent, intertemporal policy instruments, prices vs. quantities, Hotelling

Government policy response to war-expenditure shocks

Pension Contributions as a Commitment device: evidence of sophistication among time-inconsistent households

Sophisticated agents with self-control problems value commitment devices that constrain future choices. Using Australian household data, I test whether these households value commitment devices in the form of illiquid pension contributions. Applying various probabilistic choice models, the results confirm the conjecture that households with problems of self-control are more likely to invest in illiquid pensions while less likely to hold very liquid forms of assets.commitment device; pensions; intertemporal choice

Regulation in a Political Economy: An explanation of limited commitment of governments in the context of the ratchet effect

This paper offers an explanation why governments have limited commitment and are susceptible to the ratchet effect. It analyzes a two period model in which a government with full commitment regulates a firm. Each period is predated by an election. If contracts of previous governments tie newly elected governments, governments end up being unable to resist renegotiation. If previous contracts do not bind new governments and taxation has a crowding-out effect, a ratchet effect occurs which is similar, but not identical to the standard ratchet effect which is due to intertemporal non-commitment. Surprisingly, social welfare may be higher in the latter case.political economy;endogenous limited commitment;renegotiation;short run contracts

Global Liquidity Trap: A Simple Analytical Investigation

How should monetary policy cooperation be designed when more than one country simultaneously faces zero lower bounds on nominal interest rates? To answer this question, we examine monetary policy cooperation with both optimal discretion and commitment policies in a two- country model. We reach the following conclusions. Under discretion, monetary policy cooperation is characterized by the intertemporal elasticity of substitution (IES), a key parameter measuring international spillovers, and no history dependency. On the other hand, under commitment, monetary policy features history dependence with international spillover effects.Optimal Monetary Policy Cooperation, Zero Lower Bound

Commitment in intertemporal household consumption: a revealed preference analysis

We present a revealed preference methodology for analyzing intertemporal household consumption behavior. In doing so, we follow a collective approach, which explicitly recognizes that multi-member households consist of multiple decision makers with their own rational preferences. Following original work of Mazzocco (2007), we develop tests that can empirically verify whether observed consumption behavior is consistent with (varying degrees of) intrahousehold commitment. In our set-up, commitment means that households choose consumption allocations on the ex ante Pareto frontier. The distinguishing feature of our tests is that they are entirely nonparametric, i.e. their implementation does not require an a priori (typically non-verifiable) specification of the intrahousehold decision process (e.g. individual utilities). We demonstrate the practical usefulness of our methodology by means of an empirical application. For the data at hand, our results suggest using a so-called limited commitment model that allows for household-specific commitment patterns. Importantly, our application also shows that bringing intertemporal dynamics in the empirical analysis can substantially increases the discriminatory power of the revealed preference methodology.

Reporting Frequency and Substitutable Tasks

The optimal reporting frequency is an important issue in accounting. In many production settings, substitution effects across periods occur. This paper shows that the optimal reporting frequency depends on the strength of the substitution effect and on the information content of performance signals. For a subset of parameter combinations - the low-chance scenario - infrequent reporting is always efficient; for other parameter combinations – the high-chance scenario - infrequent reporting is efficient as long as first-period signals show high informativeness (and substitution effects are strong). Limited commitment by the principal does not influence results.dynamic agency, intertemporal aggregation, reporting frequency, performance measurement, substitubtable tasks, commitment

Intertemporal Distortions in the Second best

This paper studies the long run properties of intertemporal distortions in a broad class of second best economies. Our unified framework encompasses and extends many well known models, such as variants of the Ramsey taxation model with aggregate or idiosyncratic risk, and economies with incentive compatibility constraints due to limited commitment, political economy, self-enforcement or private information, or combinations of these. We identify a sufficient condition that rules out permanent intertemporal distortions: If there exists an allocation that satisfies all constraints and eventually converges to the limiting first best allocation, then intertemporal distortions are temporary in the second best. This result uncovers a common optimality principle linking the intertemporal allocation of resources with the ability to frontload distortions for this broad class of environments. A series of applications illustrates the significance of these findings.

Commitment Vs. Flexibility

This paper studies the optimal trade-off between commitment and flexibility in an intertemporal consumption/savings choice model. Individuals expect to receive relevant information regarding their own situation and tastes - generating a value for flexibility - but also expect to suffer from temptations - generating a value for commitment. The model combines the representations of preferences for flexibility introduced by Kreps (1979) with its recent antithesis for commitment proposed by Gul and Pesendorfer (2002), which nests the hyperbolic discounting model. We set up and solve a mechanism design problem that optimizes over the set of consumption/saving options available to the individual each period. We characterize the conditions under which the solution takes a simple threshold form where minimum savings policies are optimal. Our analysis is also relevant for other issues such as situations with externalities or the problem faced by a 'paternalistic' planner, which may be important for thinking about some regulations such as forced minimum schooling laws.
