The conventional linear consumption function was compared to a proposed logarithmic consumption function using collected data as the basis for studying the accuracy of each function. To kick things off, the current linear model was studied in full to lay the groundwork for sound comparison....

We formulate a general cointegrated vector autoregressive (CVAR) model that nests both a class of consumption Euler equations and various Keynesian type consumption functions. Using likelihoodbased methods and Norwegian data, we find support for cointegration between consumption, income and...

In this paper, we estimate the behavior of private consumption in Cote d’Ivoire under the permanent income hypothesis using annual data for the period 1970–2016. The first objective is to test the validity of the permanent income hypothesis in Cote d’Ivoire. Our second concern is to...

We explore intertemporal preferences that are recursive and account for local intertemporal substitution. First, we establish a rigorous foundation for these preferences and analyze their properties. Next, we examine the associated optimal consumption problem, proving the existence and...

Evidence suggests that consumers do not perfectly optimize, contrary to a critical assumption of classical consumer theory. We propose a model in which consumer types can vary in both their preferences and their choice behavior. Given data on demand and the distribution of prices, we identify...
