Equivalence scales provide answers to questions like how much a household with two children needs to spend compared to a couple to attain the same welfare level. These are important questions for child allowances, social benefits and to assess the cost of children over the life-cycle for example. We discuss equivalence scales in an intertemporal setting with uncertainty. To estimate equivalence scales we use a panel from German households (GSOEP) containing subjective data on satisfaction with life and satisfaction with income to represent the welfare level. Because satisfaction is measured on a discrete scale we use limited dependent variable models for panel data in estimation. Using satisfaction with life data we find that larger households do not need any additional income to be as satisfied as a couple. Using satisfaction with income, however, yields equivalence scales that increase with household size. 相似文献

The author examines the welfare implications of foreign aid within the framework of a two-period, two-country model of international trade. It is up to the donor country to decide what fraction of any given aid package is to be made available for the recipient's immediate consumption in period one, and what part should be allocated for investment in infrastructure that expands the recipient's production possibilities in period two. The focus of the analysis is on the conditions under which both countries agree or disagree on the manner in which the aid funds should be divided between the two options. 相似文献

It is known that in an intertemporal competitive economy, a tradable permit system may not achieve efficiency without setting appropriate permit interest rates (i.e., rewards for holding permits). To find the rates, however, we need to know in advance the path of efficient permit prices, which is difficult to obtain. This study intends to solve this problem in two ways. First, we analyze a special case in which the permit interest rates are given by a simple rule. For example, if the marginal abatement cost of pollution emission is constant, then the appropriate rate is to equal the monetary interest rate. As is the case for global warming, if the damage is caused in the future far beyond the planning period of the environmental program, the appropriate rate coincides with the marginal self-recovery of environmental stock under certain conditions. As a second approach, we propose a tradable permit system with a permit bank, as a mechanism by which the permit interest rates are generated endogenously without governmental intervention other than the issuance of permits. However, we also show that this approach raises the problem of indeterminacy of the equilibrium. 相似文献

The role of money clearly stands up in a truly irreversible process of economic change, like the building up of an altogether new productive capacity. Money has an essential role in this process, although not in the usual sense of modifying the real equilibria of the economy. As a matter of fact the problem to be faced in the context considered-where focus is on the process of change in itself rather than on its outcome-is theviability of the process of change. This paper shows that it is indeed the availability of financial resources at the right moment during the process that determines its viability, and that this stresses the fact that, out of equilibrium,real choices cannot be separated from financial decisions. 相似文献

This paper tests how subjects behave in an intertemporal consumption/saving experiment when borrowing is allowed and whether subjects treat debt differently than savings. Two treatments create environments where either saving or borrowing is required for optimal consumption. Since both treatments share the same optimal consumption levels, observed consumption choices can be directly compared across treatments. The experimental findings imply that deviations from optimal behavior are higher when subjects have to borrow than when they have to save in order to consume optimally, suggesting debt aversion. Signifiant under-consumption is observed when subjects have to borrow in order to reach optimal consumption. In line with previous experiments, weak evidence is found suggesting that subjects over-consume when saving is necessary for optimal consumption. 相似文献

This paper examines intertemporal risk-taking in a stochastically growing economy with externalities in human capital accumulation where agents have preferences for social status. In order to isolate the effects of status concerns on long-run expected growth, the analysis is embedded in a non-expected utility setting, which disentangles the effects from risk aversion and intertemporal substitution. We examine the interaction between status desire and risk, risk aversion and intertemporal substitution. The externalities generated by the status game are able to correct the allocative distortions from the knowledge spillovers.Acknowledgement The author would like to thank an anonymous referee for his valuable comments. 相似文献

The paper presents a multisectoral CGE model with overlapping generations in which intertemporal optimization by households and firms determines savings and investment under perfect foresight. We calibrate the model to Austrian data and simulate a unilateral tariff liberalization scenario. We find that unilateral tariff reductions are expansionary in the long-run but involve considerable diversity in sectoral adjustment. Foreign debt increases in the long-run, causing an improvement in the trade balance. In terms of welfare, some old generations gain at the expense of young and future generations. Budgetary policies are shown to be crucial for several effects. 相似文献

This article is devoted to a study of the optimal monetary and fiscal policies within the framework of an overlapping generations model with cash-in-advance constraints. We first characterize the intertemporal equilibrium. Then we show how to decentralize the optimal growth path using available policy instruments (i.e., labor income and capital taxes, public debt, money supply). Between the four instruments: wages and capital taxes, debt and monetary policy, one is redundant among the three last which implies that the Friedman Rule is only a special case. 相似文献

This paper provides a tractable analytical framework to study intertemporal equilibria between non-competitive supply and dynamic demand for non-durable goods. The basic hypothesis is that consumers enjoy utility from particular services rather than from commodities. Consumption of the non-durable good follows a dynamic pattern, because it depends on the stock of durables and energy demand provides the prototypical example, e.g., mobility, thermal comfort, etc. are the output of a combination of durable and non-durable goods. Indeed, turmoils in energy markets are to a great deal due to short run inflexibility and this gives this theoretical paper a topical flavour. The outcomes differ substantially across the strategic setups while differences in expectations (myopic versus rational) matter only transiently but not in the long run. 相似文献

This paper explores aggregate consumption behaviour in four developing countries under the assumption that consumers' planning horizons do not extend over their expected lifetime. Under certain conditions, the resulting ‘moving planning horizon model’ suggests that changes in current income would exert considerably more influence over current consumer spending than is predicted by forward-looking theories of consumption which typically assume that consumers' planning horizons coincide with expected lifetime. Estimation of the model for the group of developing countries provides empirical support for the role of changes in current income in influencing the consumption process. The results also reveal that consumers are relatively short-sighted sinced the length of the planning period of consumers ranges from just over ten months. An important implication of these findings is that policy measures can be effective not only if they influence consumers' permanent incomes but also if they affect changes in current income. 相似文献

In infinite horizon, a credible durable-good monopolist may resort to intertemporal price discrimination. We provide an analytical characterization of his optimal price policy when consumers and the monopolist have different values for the trade because of distinct discount factors. 相似文献

Environmental mandates can impose large costs on the businesses that must comply with them. Understanding the effects of those
costs on production decisions may require a dynamic framework if environmental damages (and the costs of complying with mandates)
depend on cumulative production or the passage of time. This paper focuses on the time dimension of general categories of
fixed and variable costs arising from different types of mandates. The paper develops an optimal control model to predict
how such costs may jointly affect current production rates, plant closure dates, and cumulative production. Theoretical results,
derived from the comparative statics of the system of equations describing the solution to that model, identify circumstances
in which the policy goals of greater production and greater environmental protection may not allways be at odds.

Summary This paper provides a theory of intertemporal pricing in a small market with differential information about the realizations of a stochastic process which determines demand. We study the sequential equilibria in stationary strategies of the stochastic game between a seller and buyer. The seller has zero cost of producing one unit of a non-durable good in all market periods. The buyer's value for the good is a random variable governed by a simple Markov process. At the beginning of each period the unit's value is determined by nature and is privately revealed to the buyer. The seller posts a single price offer each period, which the buyer either accepts or rejects. Only two types of price paths emerge in equilibrium: either prices are constant, or they have persistent cycles between a low and a high value. In both cases, however, prices are sticky in the sense that changes in price are less frequent than changes in the economy's fundamentals.We thank John Rust and Asher Wolinsky for helpful comments.

Exploitation of the marine ecosystem brings with it an intertemporal choice: there is a choice of catching the fish today, or restrain from fishing with the option of an increase in the benefit from future harvest. In a marine ecosystem under common pool management regime the contribution margin from catching the fish belongs to the fisher, while the benefit from the investment of leaving the fish in the sea will be shared in the common pool. The intertemporal choice therefore creates a driver for short sighted use of the ecosystem. The intertemporal balance of the exploitation is analyzed by applying capital theory to a size-based ecosystem model. The model reveals a need for intertemporal balance with respect to both fish size and harvest volume. The management therefore is, at an ecosystem level, to set target and regulate not only harvest volume but also size. 相似文献

If the future is uncertain, optimal intertemporal decisions rely on anticipating one's own optimal future behavior as is typical in dynamic programming. Our aim is to detect experimentally stylized facts about intertemporal decision making in a rich stochastic environment. Compared to previous experimental studies our experimental design is more complex since the time horizon is uncertain and termination probabilities have to be updated. In particular the decision task is non-stationary as in real life which seriously complicates the task of diagnosing behavioral regularities. In this study we give some illustrative results and provide some general perspectives. Our main result is that subjects' reaction to information about termination probablilities are qualitatively correct. 相似文献

This paper employs cointegration and multicointegration analysis to explore the issue of external solvency in the small open economy of Australia. Results indicate that in the fixed exchangerate era exports and imports are multicointegrated while in the more recent floating exchange-rate period the series do not share a conventional long-run equilibrium relationship. The results are consistent with intertemporal external solvency in the early period and insolvency more recently. Sustainability criteria are reviewed. Indications are that low saving and investment rates may inhibit Australia's abiliry to sustain persistent external imbalances, however, recent fiscal adjustments may work to abate this problem. 相似文献
