Are all models wrong?

September 17, 2015

If you say “All models are wrong” then the most important issue is to define the words. “All” is quite clear, “are” also is without much doubt. So, we are left with “models” and “wrong” … The more interesting discussion is the one about the definition of truth. The philosopher Bertrand Russell has written something on truth about a century ago in his book The Problems of Philosophy (ch. XII): “It will be seen that minds do not create truth or falsehood. … More Are all models wrong?

Inequality and the poverty of atomistic reductionism

September 17, 2015

The essence of this critique of the market lies in insisting on the structural relations that hold among individuals. The classic conception of the market sees individuals atomistically and therefore maintains that an individual’s holding can be justified by looking only at that individual. This was the original appeal of the libertarian picture: that the validity of an agreement could be established by establishing A’s willingness, B’s willingness, and the fact that they are entitled to trade what they are trading. Justification could be carried out purely locally. But this is not the case … More Inequality and the poverty of atomistic reductionism

Graph of the day. Employment of ‘older’ people in the EU

September 17, 2015

Employment Rate According to Eurostat, “The employment rate of older people has increased in both in the long term since 2002 and in the short term since 2009. The positive trend has been consistent for both men and women over the entire time period. Because the employment rate for older women has grown faster than for older men, the gap between men and women has narrowed slightly“. Which means that at least part of the dreaded ‘dependency’ crisis has been solved: less 55 to 64 year olds are dependent, more have a job (which means that the denominator of the dependency ratio also increased). … More Graph of the day.

Why China had to crash: Part 2 | Real-World Economics Review Blog

September 16, 2015

One thing my 28 years as a card-carrying economist have taught me is that conventional economic theory is the best guide to what is likely to happen in the economy. Read whatever it advises or predicts, and then advise or expect the opposite. You (almost) can’t go wrong. Nowhere is this more obvious than in … More Why China had to crash: Part 2 | Real-World Economics Review Blog

An $18.42 Minimum Wage? (graph)

August 17, 2015

ast year, President Obama called for increasing the federal minimum wage to $10.10 an hour by the end of 2015. He argued that after 2015, increases in the minimum wage should be tied to inflation, with the minimum wage rising in line with the consumer price index.

The purchasing power of the minimum wage peaked in the late 1960s at $9.54 an hour in 2014 dollars. That is over two dollars above the current level of $7.25 an hour. While raising the minimum wage to $9.54 would provide a large improvement in living standards for millions of workers who are currently paid at or near the minimum wage, it is worth asking a slightly different question: what if the minimum wage had kept in step with productivity growth over the last 44 years? In other words, rather than just keeping purchasing power constant at the 1968 level, suppose that our lowest paid workers shared evenly in the economic growth over the intervening years. … More An $18.42 Minimum Wage? (graph)

Why Real Business Cycle models can’t be taken seriously

August 17, 2015

They try to explain business cycles solely as problems of information, such as asymmetries and imperfections in the information agents have. Those assumptions are just as arbitrary as the institutional rigidities and inertia they find objectionable in other theories of business fluctuations … I try to point out how incapable the new equilibrium business cycles … More Why Real Business Cycle models can’t be taken seriously

The Rise of the Liquid Society

July 26, 2015

The collapse of the old system has already happened and efforts to perpetuate it are only aggravating the problem. People have experienced the reality of this shift in their everyday lives, in their vulnerability to systemic risk and sudden job losses. However governments have remained in denial, trying to apply the ‘one solution’ fits all problems model (i.e. trying to correct a private debt problem by creating more debt). Meanwhile… … More The Rise of the Liquid Society

The Keynes-Ramsey-Savage debate on probability

July 22, 2015

Neoclassical economics nowadays usually assumes that agents that have to make choices under conditions of uncertainty behave according to Bayesian rules, axiomatized by Ramsey (1931) and Savage (1954) – that is, they maximize expected utility with respect to some subjective probability measure that is continually updated according to Bayes theorem. If not, they are supposed to be irrational, and ultimately – via some “Dutch book” or “money pump”argument – susceptible to being ruined by some clever “bookie”. … More The Keynes-Ramsey-Savage debate on probability

Consumer Choice and Growing Shared Responsibility

June 28, 2015

Social media analysis reveals a growing trend towards a sense of shared responsibility. This should be a major concern for companies, because what happens when this paradigm makes the leap from humanitarian aid to consumer choice, is that socially responsible practices will become a requirement to stay in business and not an option. Smart brands will be wise to note this change in consumer attitudes, where new information is quickly translating into action. … More Consumer Choice and Growing Shared Responsibility

Modern Economics not Keeping up with Modern Times

May 29, 2015

This paper challenges the notion of “modern economics” demonstrating that existing models are not sufficient to handle the next wave of global economic disruption that will be experienced during the next 40 years. Four examples are presented to illustrate the paradigm shifts in the making. Upcoming monumental challenges require reevaluating societal needs of the 21st century and approaching modeling from a fresh perspective. Technology has moved on, so should fundamental macroeconomic assumptions. … More Modern Economics not Keeping up with Modern Times

At What Level does the Culture of Entitlement Becomes Morally Wrong?

January 30, 2015

The term ‘entitlement’ is often used in political discourse to refer to welfare and social net ‘handouts’ that create debate among liberals, realists, socialists and postructuralists alike. These debates focus around the issue of fairness considering that some people work ‘harder’ than others. However, I would like to dissect this term from the definition that … More At What Level does the Culture of Entitlement Becomes Morally Wrong?

Can we end poverty?

January 29, 2015

With so much time and effort being invested in this goal by NGO’s and governments alike, this is a question worth asking. Can we effectively end poverty at some point? And if so, what will it take? The answer depends on the measuring stick being used to define poverty. In order to mitigate any kind of problem, one must first define the parameters of the problem itself. … More Can we end poverty?
