Expected Inflation, Expected Stock Returns, and Money Illusion: What can we learn from Survey Expectations?
We show empirically that survey-based measures of expected inflation are significant and strong predictors of future aggregate stock returns in several industrialized countries both in-sample and out-of-sample. By empirically discriminating between competing sources of this return predictability by virtue of a comprehensive set of expectations data, we find that money illusion seems to be the driving force behind our results. Another popular hypothesis - inflation as a proxy for aggregate risk aversion - is not supported by the data.Inflation expectations, Money Illusion, Proxy hypothesis, Stock returns
Further Baire results on the distribution of subsequences
This paper presents results about the distribution of subsequences which are
typical in the sense of Baire.
The first part is concerned with sequences of the type x_k = n_k*alpha, n_1 <
n_2 < n_3 < ..., mod 1. Improving a result of Salat we show that, if the
quotients q_k = n_{k+1}/n_k satisfy q_k > 1+ epsilon, then the set of alpha
such that (x_k) is uniformly distributed is of first Baire category, i.e. for
generic alpha we do not have uniform distribution. Under the stronger
assumption lim q_k = infinity one even has maldistribution for generic alpha,
the strongest possible contrast to uniform distribution.
The second part reverses the point of view by considering appropriately
defined Baire spaces S of subsequences. For a fixed well distributed sequence
(x_n) we show that there is a set M of measures such that for generic (n_k) in
S the set of limit measures of the subsequence (x_{n_k}) is exactly M.Comment: 21 pages, LaTeX2e. Final version. (Somewhat expanded proofs and

Dimension and product structure of hyperbolic measures
We prove that every hyperbolic measure invariant under a C^{1+\alpha}
diffeomorphism of a smooth Riemannian manifold possesses asymptotically
``almost'' local product structure, i.e., its density can be approximated by
the product of the densities on stable and unstable manifolds up to small
exponentials. This has not been known even for measures supported on locally
maximal hyperbolic sets.
Using this property of hyperbolic measures we prove the long-standing
Eckmann-Ruelle conjecture in dimension theory of smooth dynamical systems: the
pointwise dimension of every hyperbolic measure invariant under a C^{1+\alpha}
diffeomorphism exists almost everywhere. This implies the crucial fact that
virtually all the characteristics of dimension type of the measure (including
the Hausdorff dimension, box dimension, and information dimension) coincide.
This provides the rigorous mathematical justification of the concept of fractal
dimension for hyperbolic measures.Comment: 29 pages, published versio
On the dimension of iterated sumsets
Let A be a subset of the real line. We study the fractal dimensions of the
k-fold iterated sumsets kA, defined as kA = A+...+A (k times).
We show that for any non-decreasing sequence {a_k} taking values in [0,1],
there exists a compact set A such that kA has Hausdorff dimension a_k for all
k. We also show how to control various kinds of dimension simultaneously for
families of iterated sumsets.
These results are in stark contrast to the Plunnecke-Rusza inequalities in
additive combinatorics. However, for lower box-counting dimension, the analogue
of the Plunnecke-Rusza inequalities does hold.Comment: To appear in the Proceedings of the Conference on Fractals and

Automating Exchange Rate Target Zones: Intervention via an Electronic Limit Order Book
This paper describes and analyzes “automated intervention” of a target zone. Unusually detailed information about the order book allows studying intervention effects in a microstructure approach. We find in our sample that intervention increases exchange rate volatility (and spread) for the next minutes but that intervention days show a lower degree of volatility (and spread) than non-intervention days. We also show for intraday data that the price impact of interbank order flow is smaller on intervention days than on non-intervention days. Finally, we reveal that informed banks take different positions than uninformed banks as they tend to trade against the central bank – which reflects a rational stance. Despite this position taking, the targeted exchange rate range holds and volatility, spread and price impact go down. Overall, the credible expression of an intervention band seems to achieve the desired effects of a target zone.foreign exchange, microstructure, intervention, exchange rate
Institutional and Individual Sentiment: Smart Money and Noise Trader Risk
Using a new data set on investor sentiment we show that institutional and individual sentiment proxy for smart money and noise trader risk, respectively. First, using bias-adjusted long-horizon regressions, we document that institutional sentiment forecasts stock market returns at intermediate horizons correctly, whereas individuals consistently get the direction wrong. Second, VEC models show that institutional sentiment forecasts mean-reversion whereas individuals forecast trend continuation. Finally, institutional investors take into account expected individual sentiment when forming their expectations in a way that higher (lower) expected sentiment of individuals lowers (increases) institutional return forecasts. Individuals neglect the information contained in institutional sentiment
Dimensions of some fractals defined via the semigroup generated by 2 and 3
We compute the Hausdorff and Minkowski dimension of subsets of the symbolic
space that are invariant under multiplication by
integers. The results apply to the sets , where . We prove that for such sets, the
Hausdorff and Minkowski dimensions typically differ.Comment: 22 page
