This paper proposes an empirical analytical framework for agglomeration economies based on a translog production-inverse input demand system. Estimation of the system allows us to identify effects on total factor productivity (TFP), partial factor productivity, factor prices and factor demands. It also provides a decomposition of the aggregate agglomeration elasticity into returns that arise from the increased efficiency of factor inputs and a "direct" agglomeration effect which exists over and above any factor augmentation. This enables us to indirectly address the problem of unobserved heterogeneity in factor "quality". The paper provides an empirical application of the model using firm level data for UK manufacturing and service industries. JEL Classification R12 · R15

This paper integrates seemingly disjoint studies on consumer behavior in micro and macroanalyses via an intertemporal two-stage budgeting procedure with durable goods and liquidity constraints. The model specifies an indirect utility function as a function of nondurable consumption, commodity (nondurables) prices, and durables stock, and derives the demand functions for nondurable goods. A demand function for durable goods is derived in an adjustment cost framework. The consumption growth equation accounts for relative price effects with precautionary saving, durables stock, and liquidity constraints. The stochastic discount factor is approximated by a time-varying linear function of nondurable consumption growth, commodity price growth, durables stock growth, and disposable income growth. The demand functions for six nondurable goods and services are jointly estimated with the Euler equations for bonds, stocks, and durable goods with allowance for liquidity constraints, using US data. Estimation provides new findings for intertemporal consumption and a multifactor consumption-based capital asset pricing model.
