Excess burden and the cost of inefficiency in public services provision

In this paper we revisit the literature on the economic consequences from inefficiency in public services provision. Following Dupuit (1844) and Pigou (1947) we argue that it is important to take the financing side explicitly into account. The fact that public expenditure financing must rely on distortional taxation implies that both direct and indirect costs are relevant when estimating the economic impacts of inefficiency in public services provision. Using Hicks’ compensating variation (following Diamond and McFadden (1974) and Auerbach (1985)) we show that these magnification mechanisms are not only conceptually relevant, they are also important from a quantitative point of view. Specifically, we rely on a range of estimates of public sector efficiency (from Afonso, Schuknecht and Tanzi (2005, 2006)) to illustrate numerically that the relative importance of indirect costs of public sector provision inefficiency, linked to financing through distortional taxation increases with the magnitude of the inefficiency.Government efficiency; excess burden; taxes; spending.

Maintaining price stability under free-floating: a fearless way out of the corner?

The behaviour of the exchange rate under a floating exchange rate regime for a small open economy with perfect capital mobility may appear like a managed float or even a firmer peg. We present a canonical new neo-classical synthesis open economy model where the central bank follows a strategy directed at maintaining price stability. It is shown that the behaviour of the exchange rate depends on the structure of the economy and on the nature of the relevant shocks. In the case of very open economies the exchange rate will look quasi-fixed in response to shocks stemming from the international capital markets. It is also shown that the joined endogeneity of the interest rate and the exchange rate has important implications for the empirical testing of uncovered interest rate parity.

Portuguese banks in the euro area market for daily funds

In this paper, we use the Furfine (1999) statistical procedure to identify money market operations from Payments Systems data. Given the availability of an alternative data set, recording money market operations we could confirm the accuracy of the method. We examine evidence on integration of the money market in the euro area. We ask: “how do Portuguese banks participate in the market for daily funds?” and look for a possible hierarchical structure in the market. We find strong evidence of integration and mixed evidence on hierarchical structure.

Macroeconomic adjustment to monetary union

The move to monetary union in Europe led to convergence of interest rates among the participating countries. This was associated with notable cross-country differences in the behaviour of key macroeconomic aggregates. Compared to the low interest rate countries, former high interest rate countries experienced a boom in domestic demand, a deterioration of the current account and appreciation of the real exchange rate. This paper documents the key stylised facts of this experience and provides a compact two-country model, based on the Blanchard-Yaari setup, to analyze this phenomenon. This model, though simple, is able to broadly capture the main qualitative features of the adjustment. Using this model, we show that the creation of the monetary union leads to an increase in welfare for all generations in both country groups.

Adjusting to the euro

In this paper we argue that, for a group of converging economies of the European Union, participation in the euro area has been associated with easier access to financing by domestic economic agents. Easier access to financing was a significant impulse leading to a sharp increase in households' expenditures and a corresponding fall in the savings ratio. Increased expenditure was associated with current account deficits, a sharp fall in the net foreign asset position and an increase in the households' indebtedness. At the same time there was a sizeable increase in the real exchange rate. In this paper, we show that it is possible to obtain all these qualitative features of adjustment using a simple analytical model of intertemporal equilibrium. Specifically, we consider a simple endowment economy with traded and non-traded goods populated by Blanchard-Yaari households. We also argue that the consideration of external habit formation improves the model's ability to mimic short to medium term adjustment dynamics while, at the same time, improving the plausibility of steady state effects.

Money Measures of Welfare Change Under Quantity Constraints

The purpose of this paper is to generalize the use of money measures of welfare change to situations in which the consumer faces quantity constraints. The usefulness of this approach lies in its wide scope of application, including situations of rationing. (in the strictest sense, such as those imposed during times of war), situations of markert disequilibrium and those in which there are externalities (public goods, for example).N/

Adaptive learning, persistence, and optimal monetary policy

We show that, when private sector expectations are determined in line with adaptive learning, optimal policy responds persistently to cost-push shocks. The optimal response is stronger and more persistent, the higher is the initial level of perceived inflation persistence by the private sector. Such a sophisticated policy reduces inflation persistence and inflation volatility at little cost in terms of output gap volatility. Persistent responses to cost-push shocks and stability of inflation expectations resemble optimal policy under commitment and rational expectations. Nevertheless, it is clear that the mechanism at play is very different. In the case of commitment it relies on expectations of future policy actions affecting inflation expectations; in the case of sophisticated central banking it relies on the reduction in the estimated inflation persistence parameter based on inflation data generated by shocks and policy responses.

Is time ripe for price level path stability?

In the paper, we provide a critical and selective survey of arguments relevant for the assessment of the case for price level path stability (PLPS). Using a standard hybrid new Keynesian model we argue that price level stability provides a natural framework for monetary policy under commitment. There are two main arguments in favour of a PLPS regime. First, it helps overall macroeconomic stability by making expectations operate like automatic stabilizers. Second, under a price level path stability regime, changes in the price level operate like an intertemporal adjustment mechanism, reducing the magnitude of required changes in nominal interest rates. Such a property is particularly relevant as a means to alleviate the importance of the zero bound on nominal interest rates. We also review and discuss the arguments against price level path stability. Finally, we also found, using the Smets and Wouters (2003) model which includes a wide variety of frictions and is estimated for the euro area, that the price level is stationary under optimal policy under commitment. The results obtain when the quasi-difference of inflation is used in the loss function, as in the hybrid new Keynesian model. Overall, the arguments in favour of or against price level path stability depend on the degree of dependence of private sector expectations on the characteristics of the monetary policy regime.
