Demographic Structure and Macroeconomic Trends

We analyse both empirically and theoretically the effects of changes in demographic structure on the macroeconomy, looking particular at their impact to medium-term trends. Our empirical exercise examines the impact of the proportion of the population in each age group, on growth, savings, investment, hours, interest rates and inflation using a panel VAR estimated from data for 20 OECD economies for the period 1970-2007. This flexible dynamic structure with interactions among the main variables allows us to estimate both the direct impact of demographic structure and their feedback effects. Our estimates confirm the importance of age structure, with young and old dependants having a negative impact on most macroeconomic variables while workers contribute positively. Our theoretical framework incorporates demographic heterogeneity and endogenous productivity, allowing us to study the medium-term interaction of demographic changes and savings, investment, and innovation decisions. Theoretical simulations incorporating the changes in demographic structure experienced by many OECD countries in the past decades replicate well our empirical findings. The current trend of population aging and reduced fertility, expected to continue in the next decades, is found to be a strong force in reducing output growth and real interest rates across OECD countries.

Fiscal Delegation in a Monetary Union with Decentralized Public Spending

In a monetary union, the interaction between several governments and a single central bank is plagued by several sources of deficit bias, including common pool problems. Each government has strong preferences over local spending and taxation but suffers only part of the costs of union-wide inflation and higher interest rates, creating a tendency towards excessive debt. Motivated by the evident failure of fiscal rules to restrain debt in the European context, this paper analyzes an alternative fiscal regime in which the control of sovereign debt issurance is delegated to an independent authority, while public spending decisions remain decentralized. Using a symmetric perfect-foresight model, we compare the long-run policy biases affecting a typical country across different institutional arrangements. Establishing an independent fiscal authority tends to reduce debt via three distinct channels: first, the debt aversion induced by its mandate; second, its greater patience, compared to an elected institution; and third, the internalization of common pool problems, if the authority is established at the union-wide level. Furthermore, we show that fiscal delegation is more effective in restraining debt, and more informationally efficient, than the establishment of a federal government which would centralize fiscal decisions.

Lending Relationships and Monetary Policy

Financial intermediation and bank spreads are important elements in the analysis of business cycle transmission and monetary policy. We present a simple framework that introduces lending relationships, a relevant feature of financial intermediation that has been so far neglected in the monetary economics literature, into a dynamic stochastic general equilibrium model with staggered prices and cost channels. Our main findings are: (i) banking spreads move countercyclically generating amplified output responses, (ii) spread movements are important for monetary policy making even when a standard Taylor rule is employed (iii) modifying the policy rule to include a banking spread adjustment improves stabilization of shocks and increases welfare when compared to rules that only respond to output gap and inflation, and finally (iv) the presence of strong lending relationships in the banking sector can lead to indeterminacy of equilibrium forcing the central bank to react to spread movements.

Securitization and Asset Prices

We investigate the link between securitization and asset prices and show that increases in the growth rate of the volume of ABS issuance lead to a sizable decline in bond and equity premia. Furthermore, we show that in a model where banks select their portfolio of assets and create synthetic securities, the compensation for undertaking risk decreases as securitization increases. The pooling and tranching of credit assets relaxes both the funding and the risk constraints banks face allowing them to increase balance sheet holdings. Accordingly, the drop in risk premium may be unrelated to a decline in actual risk.

Macroprudential Theory: Advances and Challenges

This note discusses recent theoretical work analyzing the causes of financial instability, its consequences for the macroeconomy, and thus the potential role for macroprudential policy. After discussing how information asymmetries and strategic complementarities can cause balance sheet losses to propagate through the financial system and over time, we discuss the role of the major classes of macroprudential instruments in preventing instability ex ante and containing it ex post. We conclude with a discussion of current challenges for macroeconomic modeling and for the design of regulation and policy.

Medium-Run Implications of Changing Demographic Structures for the Macro-Economy

In the decade since the onset of the financial crisis, the disappointing recovery has sparked renewed concern about the medium-run outlook for advanced economies. Rather than returning to the pre-crisis trend, output has continued to diverge from it. It is difficult to know whether this is a cyclical phenomenon, a slow recovery towards steady state, or a secular change in the nature of steady state growth, an indication of secular stagnation. While there may be an important, but transitory, cyclical component in the poor performance of the past decade, we will emphasise the secular forces: the impact of demographic structure and innovation. We draw on the empirical and theoretical work reported in Aksoy, Basso, Smith and Grasl (2015), ABSG, about the impact of changes in demographic structure on macroeconomic outcomes. This suggests that changes in age profile not only have significant implications for savings, investment, real interest rates and growth but also for innovation. The size of the effects seems plausible. For instance, if in 2015 the UK had the 1970 age structure, it would have added 0.68 percentage points to the long-run annual growth rate. The model suggests that the population aging predicted for the next decades will tend to reduce output growth and real interest rates across OECD countries.
