The economic theory of network externalities provides the rationale for this paper, which investigates whether adoption of network strategies in European stock exchanges creates additional value in the provision of trading services. Using unbalanced panel data from all major European exchanges...

This zip archive contains implementations of the trend-cycle-season filter in Eviews, Excel, and MatLab. The trend-cycle-season filter is another univariate method to decompose a time series into a trend, a cyclical and a seasonal component: the Trend-Cycle filter (TC filter) and its extension,...

The aims of this paper are estimate and forecast the Non-Accelerating Inflation Rate of Unemployment, or NAIRU, for Brazilian unemployment time series data. In doing so, we introduce a methodology for estimating mixed additive seasonal autoregressive (MASAR) models, by the Generalized Method of...

This paper proposes a new univariate method to decompose a time series into a trend, a cyclical and a seasonal component: the Trend-Cycle filter (TC filter) and its extension, the Trend-Cycle-Season filter (TCS filter). They can be regarded as extensions of the Hodrick-Prescott filter (HP...

The purpose of this study is therefore twofold. First, to establish the claim that currency in circulation has been rising. Second, to empirically quantify and give a full account of the reasons determining the dynamics and volatility of currency in circulation. Using annual data for the...

This paper studies the behavior of the HEGY statistics for quarterly data, for seasonal autoregressive unit roots, when the analyzed time series is deterministic seasonal stationary but exhibits a change in the seasonal pattern. As a by-product we analyze also the HEGY test for the nonseasonal...

The paper investigates some of the key factors that have influenced exchange rate movements since the foreign exchange market was liberalized in 1994. The paper adopts a general empirical specification of the exchange rate equation involving the interest rate and price differentials, as well as...

The international literature on minimum wage greatly lacks empirical evidence from developing countries. In Brazil, not only are increases in the minimum wage large and frequent but also the minimum wage has been used as anti-inflation policy in addition to its social role. This paper estimates...

Despite the shortcomings of Hayek’s spontaneous order, there is a positive side, perhaps even a positive feedback. Hayek left us with a “what if” question and returns us to that initial opening of Pandora’s Box, or perhaps the initial onset of neo-realism, neo-liberalism,...
