Traditional New Keynesian models prescribe that optimal monetary policy should aim at price stability. In the absence of a labor market frictions, the monetary authority faces no unemployment/inflation trade-off. I study the design of optimal monetary policy in a framework with sticky prices and matching frictions in the labor market. Optimal policy features deviations from price stability in response to both productivity and government expenditure shocks. When the Hosios 1990 condition is not met, search externalities make the flexible price allocation unfeasible. Optimal deviations from price stability increase with workers’ bargaining power, as firms´ incentives to post vacancies fall and unemployment fluctuates above the Pareto efficient one.
Recent empirical research suggests that measures of investor sentiment have predictive power for future stock returns at intermediate and long horizons. Given that sentiment indicators are widely published, smart investors should exploit the information conveyed by the indicator and thus trigger an immediate market response to the publication of the sentiment indicator. The present paper is the first to empirically analyze whether this immediate response can be identified in the data. We use survey-based sentiment indicators from two countries (Germany and the US). Consistent with previous research we find predictability at intermediate horizons. However, the predictability in the US largely disappears after 1994. Using event study methodology we find that the publication of sentiment indicators affects market returns. The sign of this immediate response is the same as the sign of the intermediate horizon predictability. This is consistent with sentiment being related to mispricing but is inconsistent with the sentiment indicator providing information about future expected returns.

Eucken's writings are rich in content not only from an (constitutional) economic perspective but also from an economic and business ethics perspective – an often neglected perspective of the reception of German Ordoliberalism in general and the Freiburg School of Economics in particular. The paper gives a first insight into the ethical-normative thinking of Eucken, as one of the main representatives of Ordoliberalism, and explains Eucken’s conception of Social Market Economy as a functioning and humane order as well as Eucken’s Kantian understanding of freedom. To conclude the essay tries to classify Eucken’s Ordoliberalism as a part of the spectrum of modern economic and business ethics.
