This paper surveys the first stage in the development of models of endogenous growth over the two decades between 1952 and 1973, including seminal works by Arrow, Frankel, Phelps, Uzawa, and others as faculty and graduate students who interacted in the Stanford–Chicago–MIT–Yale Nexus. The paper also deals with American Economic Association (AEA) and Econometric Society (ES) conference sessions over the period 1964–1968 on growth, technical progress, and innovations and with the contributions in the 1967 Shell volume, in addition to dissertations, working papers, and book chapters by those involved in the “first wave” over the period 1965–1973. Finally, the paper considers the initial efforts at building more sophisticated models based on technical progress, human capital, increasing returns and imperfect competition, and the incompatibility between increasing returns with competitive equilibrium.

We assess the macroeconomic effects of a sovereign restructuring in a small economy belonging to a monetary union by simulating a dynamic general equilibrium model. We compare the macroeconomic outcome of restructuring with scenarios where the debt reduction is achieved via fiscal adjustment. In line with the empirical evidence, we assume that the sovereign debt is held by domestic agents and by agents in the rest of the monetary union; after the restructuring the sovereign borrowing rate increases and the increase is fully transmitted to the domestic households' borrowing rate; and the government cannot discriminate between domestic and foreign agents when restructuring. We also assume that the small economy does not exit from the monetary union after the restructuring and that the restructuring does not have systemic effects on the rest of the union. Our results suggest that the restructuring can imply persistent and large reduction of output, especially if the share of public debt held domestically is large, the private foreign debt is high, and the spread paid by the government and the households does increases.

This paper provides long-run evidence on the dynamic effects of supply and demand shocks on commodity prices. I assemble and analyze a new data set of price and production levels of copper, lead, tin, and zinc from 1840 to 2014. Using a novel approach to identification, I show that price fluctuations are primarily driven by demand, rather than supply shocks. Demand shocks affect the price for up to 15 years, whereas the effect of mineral supply shocks persists for up to 5 years. Price surges caused by rapid industrialization are a recurrent phenomenon throughout history. Mineral commodity prices return to their declining or stable trends in the long run.

Using laboratory experiments within a New Keynesian framework, we explore the interaction between the formation of inflation expectations and monetary policy design. The central question in this paper is how to design monetary policy when expectations formation is not perfectly rational. Instrumental rules that use actual rather than forecasted inflation produce lower inflation variability and reduce expectational cycles. A forward-looking Taylor rule where a reaction coefficient equals 4 produces lower inflation variability than rules with reaction coefficients of 1.5 and 1.35. Inflation variability produced with the latter two rules is not significantly different. Moreover, the forecasting rules chosen by subjects appear to vary systematically with the policy regime, with destabilizing mechanisms chosen more often when inflation control is weaker.

This paper builds a standard search model with flexible prices and wages, and extensive and intensive labor adjustments. Money is introduced into the model through a cash-in-advance constraint in which only consumption is cash constrained. The model reproduces labor-market dynamics under a productivity shock and/or a monetary shock. I can replicate the Beveridge and Phillips curves that are observed in the data, and do not need to rely on the New Keynesian model or real wage rigidity. I find that the nonexistence of an extensive margin and different money mechanisms, such as cash constraints on investment and money in the utility function, do not change the above replications. Furthermore, I can still replicate the Beveridge curve even without money or with rigid prices.

We construct a microfounded model of money with Gul–Pesendorfer preferences. In each period, agents are tempted to spend all their money by the end of the period, and they suffer from the forgone utility that could have been obtained by adopting the tempting choice. We find that the Friedman rule may not be optimal. A positive nominal interest rate improves welfare because it reduces the real money balances and renders the temptation less attractive. The welfare gained by deviating from the rule is equivalent to 0.67% of consumption.

We formulate an overlapping-generations model with household heterogeneity and productive and nonproductive government programs to study the macroeconomic and intergenerational welfare effects of risk premium shocks and government debt reductions. We demonstrate that in a small open economy with a high level of debt, a small increase in the risk premium of the interest rate leads to a substantial contraction in output and negative welfare effects. We then quantify the effects of reducing the debt-to-gross-domestic-product ratio using a wide range of fiscal austerity measures. Our results indicate trade-offs between short-run contractions and long-run expansions in aggregate output. In the short run, spending-based austerity reforms are worse than tax-based reforms in terms of lost income. However, in the long run, spending-based reforms produce higher output than tax-based reforms. In addition, welfare effects vary significantly across generations, skill groups, and working sectors. The current old and middle-aged generations experience welfare losses, whereas future generations are beneficiaries of the reforms.
