On 9 July 1849, Victor Hugo pronounced his speech "destroying misery" at the French Legislative Assembly. Whether in France or in the rest of the world, no one has succeeded, except China from 1980 to 2019, before the Covid crisis.In one side, in order to share a common direction with all...

The notion of Wealth is not well defined. It has been the subject of famous treaties, such as those of Anne-Marie Turgot, Auguste Léon Walras and then Adam Smith, but it has not been defined. It is very simple to check. Who's the richest? A person with a patrimony of 300 000 dollars and...

Gdp even net of obsolescence (ndp) has to be considered only as an expense (investment is an expense; consumption, export minus import, and change of stock, all these indicators are today expenses). As entrepreneur you will never manage your investments by looking only the expenses, it is clear...

The two Cambridge controversy have marked a milestone in economic thinking.

From its publication in The Times in 1933, John Maynard Keynes’s investment multiplier sparked much debate and controversy. Can an investment generate 3 or 4 times its value in income within one year? To date, no one has questioned the theoretical merits of this multiplier. Even the biggest...

We provide a continuous-time "risk-centric" representation of the New Keynesian model, which we use to analyze the interactions between asset prices, financial speculation, and macroeconomic outcomes when output is determined by aggregate demand. In principle, interest rate policy is highly...

Should monetary policymakers raise interest rates during a boom to rein in financial excesses? We theoretically investigate this question using an aggregate demand model with asset price booms and financial speculation. In our model, monetary policy affects financial stability through its impact...

In this paper we: (i) provide a model of endogenous risk intolerance and serve aggregate demand contractions following a large (non-financial) shock; and (ii) demonstrate the effectiveness of Large Scale Asset Purchases (LSAPs) in addressing these contractions. The key mechanism stems from...
