This paper builds a small-open-economy nonscale-growth model with negative population growth and investigates the relationship between trade patterns and per capita consumption growth. Under free trade, if the population growth rate is negative and its absolute value is small, the home country becomes an agricultural country. Then the long-run growth rate of per capita consumption is positive and depends on the world population growth rate. On the other hand, if the population growth rate is negative and its absolute value is large, the home country becomes a manufacturing country. Then the long-run growth rate of per capita consumption is positive and depends on both the home country and the world population growth rates. Moreover, the home country is better off under free trade than under autarky in terms of per capita consumption growth irrespective of whether the population growth is positive or negative.

This paper uses hedonic regression techniques to decompose the price of a house into land and structure components using real estate sales data for Tokyo. To get sensible results, a nonlinear regression model using data that covered multiple time periods was used. Collinearity between the amounts of land and structure in each residential property leads to inaccurate estimates for the land and structure value of a property. This collinearity problem was solved by using exogenous information on the rate of growth of construction costs in Tokyo in order to get useful constant-quality subindices for the price of land and structures separately.

In this paper, I analyze an optimal loan contract between a risk-neutral financial intermediary and a risk-averse household, where the household receives a stochastic endowment stream that grows over time and is unable to commit to the contract. I examine the household's welfare in the equilibrium contract, and find that, first, under sufficiently rapid endowment growth, the presence of uncertainty in endowment may improve the household's welfare through relaxation of its commitment problem, and second, regardless of the endowment growth rate, the household's welfare is nonincreasing in the persistence of endowment. Numerical analysis suggests that welfare improvement from uncertainty may occur under reasonable parameters. These results have potentially important practical implications—for example, for developing countries that rely on external borrowing.

This paper is an up-to-date survey of the state of the art in dynamical systems theory relevant to high levels of dynamical complexity, characterizing chaos and near-chaos, as commonly found in the physical sciences. The paper also surveys applications in economics and finance. This survey does not include bifurcation analyses at lower levels of dynamical complexity, such as Hopf and transcritical bifurcations, which arise closer to the stable region of the parameter space. We discuss the geometric approach (based on the theory of differential/difference equations) to dynamical systems and make the basic notions of complexity, chaos, and other related concepts precise, having in mind their (actual or potential) applications to economically motivated questions. We also introduce specific applications in microeconomics, macroeconomics, and finance and discuss the policy relevance of chaos.

The main result is that the golden rule equilibrium (GRE) is Pareto optimal (in the classical sense) in an overlapping generations (OG) model with constant-returns-to-scale production, transfers, arbitrary life-time productivity and homogeneous instantaneous felicity. In addition, we extend Cass and Yaari's equivalence between efficiency (aggregate consumption dominance) and present value dominance (with evaluation made using a candidate equilibrium price path).

Aggregate hours worked per working-age person decreased in Austria by 25% from 1970 to 2005. During the same time period, taxes increased, particularly the effective marginal tax rate on labor income. Using a standard general equilibrium growth model with taxes, I quantitatively assess the role played by the evolution of taxes in the evolution of hours worked in Austria. The model accounts for 76% of the observed decrease in hours worked per working-age person. My results are in line with other studies, which find taxes play an important role in explaining aggregate hours worked.

This paper investigates the effects of R&D subsidies on aggregate product variety and endogenous productivity growth without scale effects. In a two-country model with imperfect knowledge diffusion, the larger country has a greater share of firms with higher productivity levels. The concentration of relatively productive firms increases knowledge flows between firms, causing an increase in firm-level employment in innovation. Accordingly, the aggregate growth rate is higher when counties are asymmetric than when they are similar in size. The larger scale of firm-level innovation activity reduces market entry, however, and aggregate product variety falls. In this framework, national R&D subsidies have positive effects on the industry share, relative productivity, and wage rate of the implementing country. If the smaller country introduces an R&D subsidy, aggregate product variety rises and productivity growth falls. If the larger country introduces an R&D subsidy, productivity growth rises, but aggregate product variety may rise or fall.

We use a two-sector neoclassical open economy model with traded and nontraded goods and endogenous markups to investigate the effects of temporary fiscal shocks. One central finding is that theory can be reconciled with evidence once we allow for endogenous markups and assume that the traded sector is more capital-intensive than the nontraded sector. More precisely, although both ingredients are essential to produce the real exchange rate depreciation, only the second ingredient is necessary to account for the simultaneous decline in investment and the current account, in line with the evidence.

Shimer (Mismatch, American Economic Review 97, 1074–1101 [2007]) introduced a model of mismatch in which limited mobility of vacant jobs and unemployed workers provides a microfoundation for their coexistence in equilibrium. He assumed that the short side of a local labor market receives all the gains from trade. In this note I show that modifying this assumption on wage-setting can deliver more reasonable predictions for wages at the level of the local market and in the aggregate.

In structural VARs, unexpected monetary tightening often leads to the price puzzle, a counterintuitive increase in inflation in the impulse response function. The identification of impulse responses requires at least a minimal set of structural assumptions, and models exhibiting the price puzzle typically use standard assumptions focusing mainly on relationships among contemporaneous disturbances. This note uses a well-established stylized fact, the long lags of monetary policy, to motivate a simple additional identifying assumption. The assumption eliminates a single term in one equation of the reduced form, and with it the price puzzle.
