Facing Greece’s lost generation

A few days ago I flew to Athens on a private visit. I had not been in the Greek capital for almost a year and I was ready to face the gloom of a place in recession. The beautiful light of Attica showered the surroundings and at first I found it difficult to detect any signs of the acute economic crisis the country faces. Additionally, the fact that I stayed at a quiet neighbourhood far away from the city centre made me question whether the media have been overreacting once again with their reports about an economy and society in unprecedented crisis

The radicalisation of lower middle class Greek families was the key to Syriza’s victory

A number of commentators have written on the extent to which Syriza managed to attract the backing of a wide section of Greek society in its election victory on 25 January. Vasilis Leontitsis writes that one of the key dynamics in the election was the support Syriza received from lower middle class families. He argues that while such families had tended to vote conservatively in previous elections, the net effect of the country’s economic crisis was to radicalise this section of the electorate and push them toward parties with more radical platforms

Nonlinear Noise Estimation in International Capital Markets

We analyzed six stock exchange markets through the nonlinear dynamics concept. We used daily data from the Toronto Stock Exchange, NYSE, London Stock Exchange, Hong Kong Stock Market, Tokyo Stock Exchange, and the Singapore Stock Exchange. The period studied is from January 1, 1988 to June 30, 1999. We performed Local Principal Components Analysis in order to estimate the dimension of each underlying attractor. Our main interest is the noise level estimation of each time series. The results indicate weak determinism and strong noise influence. The noise-to-signal ratio for almost all time series is above 50%. Noise is leptokurtic in the eastern stock markets, and mesokurtic in western ones

Accounting for outliers and calendar effects in surrogate simulations of stock return sequences

Surrogate Data Analysis (SDA) is a statistical hypothesis testing framework for the determination of weak chaos in time series dynamics. Existing SDA procedures do not account properly for the rich structures observed in stock return sequences, attributed to the presence of heteroscedasticity, seasonal effects and outliers. In this paper we suggest a modification of the SDA framework, based on the robust estimation of location and scale parameters of mean-stationary time series and a probabilistic framework which deals with outliers. A demonstration on the NASDAQ Composite index daily returns shows that the proposed approach produces surrogates that faithfully reproduce the structure of the original series while being manifestations of linear-random dynamics.Comment: 21 pages, 7 figure

Incomplete municipal government reforms and a lack of funding in Greece mean that Athens is still central to regional decision-making

In the past two years, Greece has fundamentally transformed the roles and responsibilities of its local government authorities. More responsibilities were granted, while the number of municipalities was reduced by 95 per cent. Vasilis Leontitsis argues that these reforms are promising. However, Greece needs to provide additional financial support for its local authorities
