Protein interaction is crucial for building networks in the brain

See on Scoop.itSocial Neuroscience Advances

Neural networks are formed by the interconnection of specific neurons in the brain. The molecular mechanisms involved in creating these connections, however, have so far eluded scientists.

Stagflation and the Rejection of Keynesian Economics: A Case of Naive Falsification

See on Scoop.itBounded Rationality and Beyond

Abstract

In this paper I employ Imre Lakatos’s methodology of scientific research programs to scrutinize the idea that stagflation in the 1970s falsified the Keynesian research program. I point out that Keynesian models were able to account for stagflation once they included inflation expectations, so the essential tenets of the Keynesian research program are consistent with the would-be anomaly of stagflation. Furthermore, Keynesian economics exhibited both theoretical and empirical progress by evolving in a way that rendered stagflation a logical consequence of Keynesian assumptions. The transition to new classical economics did not yield such progress. Also, as Keynesian economics tends to adopt novel findings and research methods, new classical economics does not have excess theoretical or empirical content relative to the Keynesian research program. In summary, I find that the falsification of the Keynesian program is unwarranted.

Behavioral Public Economics Welfare and Policy Analysis wit Non-Standard Decision-Makers

See on Scoop.itBounded Rationality and Beyond

Abstract: This paper has two goals. First, we discuss several emerging approaches to applied welfare analysis under non-standard (“behavioral”) assumptions concerning consumer choice.
This provides a foundation for Behavioral Public Economics. Second, we illustrate applications of these approaches by surveying behavioral studies of policy problems involving saving, addiction, and public goods. We argue that the literature on behavioral public economics, though in its infancy, has already fundamentally changed our understanding of public policy in each of these domains.

Optimal time-consistent fiscal policy in an endogenous growth economy with public consumption and capital

See on Scoop.itBounded Rationality and Beyond
Abstract

In an endogenous growth model where the fiscal authority cannot commit to policy decisions beyond the current period, we explore the time-consistent optimal choice for two policy instruments: the income tax rate and the split of government spending between utility bearing consumption and productive services to firms. We show that under the time-consistent Markov policy the economy lacks any transitional dynamics and there is local and global determinacy of equilibrium. For empirically plausible parameter values we find that the Markov-perfect policy implies a higher tax rate and a larger proportion of government spending allocated to consumption than those chosen under a commitment constraint. As a result, economic growth is slightly lower under the Markov-perfect policy than under the Ramsey policy, with growth under lump-sum taxes being highest. The implication of our results is that if the private sector is aware of the government’s inability to pledge future policy decisions, then the government should impose a slightly higher tax rate and devote a higher share of public resources to consumption, with a relatively low cost in terms of growth.

Was the European sovereign crisis self-fulfilling? Empirical evidence about the drivers of market sentiments

See on Scoop.itBounded Rationality and Beyond
Abstract

We investigate the presence of self-fulfilling dynamics during the European sovereign crisis in the light of a theoretical model that we bring to the data. Our empirical framework allows us to empirically test the presence of self-fulfilling dynamics and to identify what may have driven the market sentiment during this crisis. To do so we estimate the probability of default of five European “peripheral” countries during January 2006 to September 2011 with a panel smooth threshold regression. Our estimation results suggest that (1) both the fundamentals and “animal spirit” ignited the European sovereign crisis; (2) we isolate the risk indicator through which investors’ belief coordinate.

Your brain on improv

See on Scoop.itBounded Rationality and Beyond

Musician and researcher Charles Limb wondered how the brain works during musical improvisation – so he put jazz musicians and rappers in an fMRI to find out. What he and his team found has deep implications for our understanding of creativity of all kinds.
