The author systematically examines one of the important issues of information — establishing the market price. He introduces the concept of «search» — where a buyer wanting to get a better price, is forced to question sellers. The article deals with various aspects of finding the necessary information.

The financial market turmoil in 2007 and 2008 has led to the most severe financial crisis since the Great Depression and threatens to have large repercussions on the real economy The bursting of the housing bubble forced banks to write down several hundred billion dollars in bad loans caused by mortgage delinquencies At the same time, the stock market capitalization of the major banks declined by more than twice as much While the overall mortgage losses are large on an absolute scale, they are still relatively modest compared to the $8 trillion of US stock market wealth lost between October 2007, when the stock market reached an all-time high, and October 2008 This paper attempts to explain the economic mechanisms that caused losses in the mortgage market to amplify into such large dislocations and turmoil in the financial markets, and describes common economic threads that explain the plethora of market declines, liquidity dry-ups, defaults, and bailouts that occurred after the crisis broke in summer 2007 To understand these threads, it is useful to recall some key factors leading up to the housing bubble The US economy was experiencing a low interest rate environment, both because of large capital inflows from abroad, especially from Asian countries, and because the Federal Reserve had adopted a lax interest rate policy Asian countries bought US securities both to peg the exchange rates at an export-friendly level and to hedge against a depreciation of their own currencies against the dollar, a lesson learned from the Southeast Asian crisis of the late 1990s The Federal Reserve Bank feared a deflationary period after the bursting of the Internet bubble and thus did not counteract the buildup of the housing bubble At the same time, the banking system underwent an important transformation The

Deciphering the Liquidity and Credit Crunch 2007-2008

This paper summarizes and explains the main events of the liquidity and credit crunch in 2007-08. Starting with the trends leading up to the crisis, I explain how these events unfolded and how four different amplification mechanisms magnified losses in the mortgage market into large dislocations and turmoil in financial markets.

Deciphering the Liquidity and Credit Crunch 2007-08

We study economic growth and inflation at different levels of government and external debt. Our analysis is based on new data on forty-four countries spanning about two hundred years. The dataset incorporates over 3,700 annual observations covering a wide range of political systems, institutions, exchange rate arrangements, and historic circumstances. Our main findings are: First, the relationship between government debt and real GDP growth is weak for debt/GDP ratios below a threshold of 90 percent of GDP. Above 90 percent, median growth rates fall by one percent, and average growth falls considerably more. We find that the threshold for public debt is similar in advanced and emerging economies. Second, emerging markets face lower thresholds for external debt (public and private)--which is usually denominated in a foreign currency. When external debt reaches 60 percent of GDP, annual growth declines by about two percent; for higher levels, growth rates are roughly cut in half. Third, there is no apparent contemporaneous link between inflation and public debt levels for the advanced countries as a group (some countries, such as the United States, have experienced higher inflation when debt/GDP is high.) The story is entirely different for emerging markets, where inflation rises sharply as debt increases.

Children’s first names and immigrationbackground in France

This paper deals with two elements of Thomas Kuhn (1962) ideas regarding paradigm: Depletion and resiliency. The possibility of paradigm depletion taking resilience into account, given the hierarchy among scientists, is modeled as a Stackelberg differential game between editors [leaders] and authors [followers]. A number of results emerge from the model: i) Paradigm depletion can be optimal; ii) The optimal editor's shadow price of potential knowledge must be non-positive, if it is positive, the editor is just a keeper of the orthodoxy rather than a scientist; iii) Editor's and/or researcher's impatience is always bad for science; iv) In equilibrium editor's behavior does not matter for optimal research effort, while only editor's behavior matter for the paradigm.

Paradigm depletion, knowledge production and research effort

Remuneration a la piece ou au merite : une modelisation du comportement academique par la theorie des jeux a champ moyen Cet article mobilise la theorie des jeux a champ moyen (Lasry et Lions [2007]) pour analyser la productivite des chercheurs. Il formalise le comportement optimal des chercheurs sous differents regimes d’incitation et fournit une justification theorique de la persistance de la loi de Lotka. Il montre qu’un systeme de remuneration discriminant les chercheurs en fonction de leur production scientifique peut induire un plus grand nombre d’entre eux a depasser un niveau de production minimal. Le systeme de remuneration au merite apparait alors comme superieur a la remuneration a la piece.

Piecework versus merit pay: a mean field games approach to academic behavior

This paper develops a simple model of the market for academic publications in business and economics. The supply of papers is presented as the outcome of a game between researchers and schools’ deans under imperfect information about the quality of a given paper. The demand for papers brings into the picture the editorial selection process. After defining the equilibrium of this market, the model allows us to study the consequences of more powerful incentives for publication in major journals. It turns out that too large bonuses, as implemented by business schools in the recent years, might bring about several unpleasant consequences, such as a drop in the quality of major journals, a decline in the number of top-tier publications realized by leading research institutions and a fall in the expected compensation of top researchers.
