Animal spirits, lumpy investment and
endogenous business cycles
Going well beyond Real Business Cycle or New-Keynesian
perspectives, this evolutionary model with fully micro-founded heterogeneous
bounded-rational agents is able to generate self-sustaining patterns
of long-term growth and endogenous business cycles.
The model can replicate the most important stylized
facts concerning micro- and macro-economic dynamics, e.g. that investment
is more volatile than GDP; consumption
is less volatile than GDP; investment, consumption and change in
stocks are procyclical and coincident variables; employment
is procyclical; un-employment
rate is anticyclical; firm size distributions are skewed but depart
from log-normality; firm growth distributions are tent-shaped.
It doesn't rely on rational expectations nor
on one fictious representative agent.

crisis without end: The consequences of
neoliberalism run amok (March 2013)
Instead of fostering innovation,
productivity and raising wages
to sustain consumption, Europe undermined
the income and demand generation process via wage stagnation and
widened income inequality. The stimulus from German re-unification
and the low interest rate convergence
produced by creation of the euro prompted a ten year credit
and asset price bubble that created fictitious prosperity. Postponing
stagnation in this fashion has had costs because it worsened the
ultimate stagnation by creating large build-ups of debt, which frame
austerity as never ending self-propelling dynamics.
Long-term macroeconomic data for 136 countries

The most user-friendly distribution of the main
international database on GDP components (consumption, investment,
public expenditure and net exports) for 136 countries and 42 years.
Excellent for international comparisons, long-term growth enquiries
and business cycle analysis, since it provides real values at constant
prices comparable over time and countries.

Inflation expectations: an empirical assessment
In this study, the presence of a marked degree
of heterogeneity in the process of expectation formation is demostrated,
using a large longitudinal survey: the Survey of Consumer Attitudes
and Behavior, conducted by the Survey Research Center (SRC) at the
University of Michigan, available at a monthly frequency from 1978.
The financial crisis, austerity and the perspective of failure
The turmoil in the Eurozone is due to the global
crisis of financialisation that broke out in 2007. But it is also
due to the biased nature of the European Monetary Union (EMU). Systematic
pressure on labour has intensified the disparities of competitiveness
among Eurozone members, splitting the Eurozone into core
and periphery. The competitiveness of the core has benefited
from extraordinary pressure on workers' wages
which, in Germany, has meant practically stagnant real wages for
well over a decade. Loss of competitiveness has entailed systematic
current account deficits
for the periphery, mirrored by equally systematic surpluses for
Germany. The eruption of generalised instability in late 2009 reflects
these profound imbalances within the Eurozone.
Rescuing the banks has come at the cost of austerity,
with negative implications for European economies and societies.
Austerity will compress public expenditure
and weaken private consumption, i.e.
the elements of aggregate demand that have shown some vitality during
the recession of 2008-9. Given the collapse of investment and the
retreat of credit, austerity has increased the risk of recession.

A new approach to business fluctuations: heterogeneous
interacting agents, scaling laws and financial fragility
Business fluctuations in
GDP, investment, etc. can be explained in a new way. The authors
present a simple agent-based model, whose core is the interaction
of heterogeneous financially fragile firms and a banking sector.
In their framework, the origin of business fluctuations can be
traced back to the ever changing configuration of the network of
heterogeneous interacting firms.
Simulations of the model
replicate surprisingly well an impressive set of stylized facts,
particularly two well known universal laws.

Cognitive macroeconometrics paradoxes
Using data from the Business Surveys Unit of
the European Commission as a long-running-continental-scale experiment,
this paper examines how, and how accurately, people assess economic
systems. Data show that people know the past better than the future
and that there is a systematic bias in forecasts.
A model of primary and secondary waves
in investment cycles
The large degree of independence of regional
and sectoral economic variables with respect to their macroeconomic
aggregates suggests that macroeconomic fluctuations are a consequence
of microeconomic disturbances, rather than the reverse.
Uniting Schumpeter's concern for innovation with
Keynes' concern for uncertainty and expectations formation, this
article focuses on the behaviour of entrepreneurs confronting uncertainty
caused by innovation. Entrepreneurs' behaviour is reconstructed
by modelling the functioning of their cognitive processes when innovations
appear. Recognition of the possibilities opened up by a successful
innovation generates a state of optimism in the minds of single
entrepreneurs, which eventually propagates to the whole economy
triggering an investments upswing. Likewise, unsuccessful innovations
can trigger a downswing.
