How closely do banks manage vault cash?

This article examines daily vault cash balances in the Eighth Federal Reserve District to see if banks have been optimizing their vault cash levels. Recent reductions in reserve requirements have not been accompanied by significant reductions in vault cash. This situation suggests that banks may be managing vault cash reserves primarily as precautionary balances to satisfy daily fluctuations in deposits and withdrawals, rather then part of total reserve management. In 1997, some larger banks instituted formal management of vault currency. If this practice spreads, it will have implications for monetary policy and cash operations.Bank reserves ; Cash management

Seasonal production smoothing

Empirical tests of the production-smoothing hypothesis have yielded mixed results. In this paper, Donald Allen looks for, and finds evidence of, seasonal production smoothing in 15 out of 25 manufacturing series and 8 out of 10 retail series, using detrended seasonally unadjusted data. The equivalent test using seasonally adjusted data were negative for all 35 series. The results suggest that seasonally adjusted data obscure short-term production-smoothing.Business cycles ; Productivity ; Seasonal variations (Economics)

Income inequality and minimum consumption: implications for growth

We propose a model that recognizes hierarchical goods and income inequality among households. The model demonstrates that growth is impacted not by inequality per se, but "absolute" income distribution or the level of poverty underlying the income distribution. Specifically, when a large fraction of the population is below the threshold income necessary for subsistence, aggregate consumption is depressed. In low-income countries, high inequality of income retards consumption growth, whereas in high-income countries inequality may be neutral for growth. Cross-country regressions indicate a positive and significant relationship between the middle quintile share of income and aggregate consumption. In all cases analyzed, increasing income in the middle quintile increases consumption growthIncome distribution ; Consumption (Economics)

A state space forecasting model with fiscal and monetary control

In this paper we model the U.S. economy parsimoniously in an a theoretic state space representation. We use monthly data for thirteen macroeconomic variables. We treat the federal deficit as a proxy for fiscal policy and the fed funds rate as a proxy for monetary policy and use each of them as control (exogenous) variables, and designate the rest as state variables. The output (measured) variable is the growth rate of quarterly real GDP which we interpolate to obtain a monthly equivalent. We specify a linear relation between state variables and implicitly allow for time variation of the relationship by using a recursive least squares (RLS) with forgetting factor algorithm to estimate the coefficients. The model coefficients are also estimated using ordinary least squares (OLS) and the resulting forecasts (in-sample and out-of-sample) are compared. The RLS algorithm performs better in the out-of-sample forecasts, particularly for those state variables which exhibit the greatest cyclical variations. Variables which had greater stability were forecasted more precisely with OLS estimated parameters.Forecasting ; Econometric models
