Empirical analysis often motivated David's new developments in econometric methodology, as when Ericsson, Hendry and Prestwich (1998) were model­ling UK money demand on an extended dataset.

That analysis led to a formal treatment of expansions of information sets, itself laying the groundwork for saturation techniques. Conversely, David would also almost immediately apply new methodological developments to ongoing empirical analyses, as when incorporating the Engle-Granger cointegration test into Hendry and Ericsson's (1983) empirical analysis of UK money demand. While David's empirical analyses cover many aspects of the economy for many countries and regions, five modelling endeavours stand out: housing and mortgage markets, consumers' expenditure, money demand, television advertising, and climate change. This section examines those endeavours.
