In earlier work (Fuhrer 1996), I document what I view as the failure of standard models of representative consumer and firm behavior to replicate the dynamics that we observe in the aggregate data. In essence, these models fail because they imply that both inflation and real variables must “jump” in response to monetary policy (and other) shocks, in contrast to identified VAR evidence that show...
Recent theoretical contributions have suggested consumption externalities or external habit formation as a potential explanation for some of the puzzles documented in the literature on finance and consumption. Furthermore, social interactions or peer-group effects are likely to be an important determinant of individual utility derived from consumption. However, the empirical relevance of these ...
The compulsive nature of weight loss behaviors central to anorexia nervosa (AN), such as relentless self-starvation and over-exercise, has led to the suggestion of parallels between AN and other compulsive disorders such as obsessive-compulsive disorder (OCD) and addictions. There is a huge unmet need for effective treatments in AN, which has high rates of morbidity and the highest mortality ra...
Neurons that fire in relation to licking, in the ventral part of the dorsolateral striatum (DLS), were studied during acquisition and performance of a licking task in rats for 14 sessions (2 h/d). Task learning was indicated by fewer errors of omission of licking and improved movement efficiency (i.e., shorter lick duration) over sessions. Number of licks did not change over sessions. Overtrain...
