Optimism appears to have rebounded after a period of low consumer confidence and sluggish consumer spending growth. The growing number of single-person households is driving increased demand for products catering to single consumers, such as single-serve ready meals and other packaged food, and this is expected to continue in coming years.
The reason is that central banks react to variables, such as inflation and the output gap, which are endogenous to monetary policy shocks. Endogeneity implies a correlation between regressors and the error term, and hence, an asymptotic bias.
In principle, Instrumental Variables IV estimation can solve this endogeneity problem.
In practice, IV estimation poses challenges as the validity of potential instruments also depends on other economic relationships. We argue in favor of OLS estimation of monetary policy rules.
To that end, we show analytically in the three-equation New Keynesian model that the asymptotic OLS bias is proportional to the fraction of the variance of regressors accounted for by monetary policy shocks.
Using Monte Carlo simulation, we then show that this relationship also holds in a quantitative model of the U. As monetary policy shocks explain only a small fraction of the variance of regressors typically included in monetary policy rules, the endogeneity bias is small.
Using simulations, we show that, for realistic sample sizes, the OLS estimator of monetary policy parameters outperforms IV estimators.May 04, · PURCHASING AND SUPPLY CHAIN MANAGEMENT DEFINITIONS AND CLARIFICATION PURCHASING Purchasing is the act of buying the goods and services that a company needs to operate and/or manufacture products.

Shopping is an activity in which a customer browses the available goods or services presented by one or more retailers with the potential intent to purchase a suitable selection of them.
A typology of shopper types has been developed by scholars which identifies one group of shoppers as recreational shoppers, that is, those who enjoy shopping and view it as a leisure activity. Optimism appears to have rebounded after a period of low consumer confidence and sluggish consumer spending growth.
The growing number of single-person households is driving increased demand for products catering to single consumers, such as single-serve ready meals and other packaged food, and this is expected to continue in coming years.
This statistic features the results of an online survey conducted in U.S. households of different income groups were asked how often they go grocery shopping in a store. The findings.
