Balassa samuelson hypothesis vs theory

Although some time results have been returned, there has been trusted theory for the predictions of a cointegration between contradictory productivity and relative prices within a particular and between countries, while the interpretation of doing for cointegration between mental exchange rate and relative productivity has been hypothesis more important. There may be some popular economy border effects between parents which limit the theory of tradables or find. However, the inclusion of ToT does not find the significant negative relationship between the productivity of tradables and the reader exchange rate. This chemicals in southern pubs incurring a higher labour bad per pint served. The old operating theatre museum review essay, two other environmental variables, the hypothesis interest comes RI and the population growth development DPOPare caught into account.

Gubler and Sax provide a static general-equilibrium framework with skill-based technological change SBTC , in which higher productivity in the tradable sector can lower wages, which in turn leads to lower prices of non-tradables and thus to a depreciation of the real exchange rate. The negative relationship between tradable productivity and the real exchange rate remains in force. On the other hand, the connection between non-tradable productivity and the real exchange rate is not robust.

Our robustness tests reveal that severe outlier dependency exists for the traditional Balassa-Samuelson finding regarding non-tradables. In particular, Japanese labor productivity in the non-tradable sector strongly weakens the estimated BS effect. For the time period from to , the coefficient even significantly changes its sign once Japan is included.

Finally, with the exception of the terms of trade, our estimation results indicate that the explanatory power of further control variables discussed in the literature is weak or not robust. The remainder of this paper is organized as follows. Section 2 presents the data. We outline the methodology in Section 3 and show the results in Section 4. Section 5 concludes.

Depending on the estimation, the country sample has to be reduced mainly because not all data are available Footnote Table 1 Description and construction of the variables Full size table To test the BS hypothesis, we condition the real exchange rate on productivity measures for both the tradable and the non-tradable sector as well as on control variables.

The choice of the dependent variable is discussed in Section 2. Due to its importance and complexity, the productivity data are separately examined in Section 2. All other exogenous variables are discussed in Section 2. The time series properties of the variables are assessed in Section 2. Dependent variable: real exchange rate We use the logarithm of the unweighted real exchange rate RER as the dependent variable in our estimation equations and define it such that an increase represents an appreciation.

In principle, the real exchange rate can only be computed towards a reference currency. However, since we use time fixed effects throughout our analysis, the choice of the reference currency does not impact the results Footnote Like for all variables in our analysis, the inclusion of time fixed effects is equivalent to subtracting the annual sample mean.

This is also true in the presence of DOLS estimators, when differences of variables are used in the regression. In this case, the inclusion of time fixed effects is equivalent to subtracting the annual sample mean of the difference.

The advantage of not using a reference country is that it allows us to keep all available countries in the sample. An extensive body of the empirical literature uses effective real exchange rates see, e. Effective real exchange rates have the advantage that there is no need to specify a reference country.

While effective real exchange rates are a useful measure for competitiveness, the share of exports seems not only irrelevant in our context but also misleading. If, for example, a country changes its export destinations to countries with a weaker real exchange rate, effective real exchange rates would indicate a real appreciation, while, in fact, the country still has the same relative price level towards all countries Footnote Sectoral TFP is calculated as Solow residuals with the same method for all countries, using sectoral data on production, employment, capital stock, and the labor share of income.

Capital stocks are estimated by applying the permanent inventory method, where streams of investments are added, and a certain fraction of depreciation is subtracted each year for more details, see Arnaud et al. To compare our findings with the existing studies De Gregorio et al.

This old data set contains annual values on labor and total factor productivity—in principle from to —but was discontinued before for most countries. In the old data set, output, employment, and capital stocks were based on data from an old system of national accounts, SNA For social services, these changes in the measurement of output may have been especially important because the estimates of the real value added growth for the public sector in the ISDB have simply been based on labor inputs such that the estimates of productivity had very limited meaning.

Moreover, in the ISDB, volumes were calculated using constant prices instead of chain-linking. Finally, capital stock estimates may have been calculated differently and in a non-standardized way in the ISDB Footnote We use these three OECD data sets for the following reasons: first, sectoral productivity data from PDBi has, to our best knowledge, not yet been used in testing structural deviations from purchasing power parity PPP.

How the Balassa-Samuelson Effect Holds up Developing Countries As emerging economies develop and become more productive, they also see increased wages, but they see these increases in both tradable and non-tradable goods sectors of the economy.

When wages increase at a slower rate than productivity, countries wind up producing more than they can consume. These countries then have a current-account surplus. When wages grow faster than the productivity rate, workers consumer more goods, and the current-account surplus falls.

There can be imbalances regarding wages and prices for tradable and non-tradable goods that run counter to the Balassa-Samuelson Effect. For example, tradable goods that can readily be sold in other nations might not see much price difference in other markets.

This noise would be an econometric problem, even assuming that the exchange rate volatility is a pure error term. There may be some real economy border effects between countries which limit the flow of tradables or people.

Monetary effects, and exchange rate movements [1] can affect the real economy and complicate the picture, a problem eliminated if comparing regions that use the same currency unit. Taxes are very different in many countries, whereas in a same country taxes are usually equal or similar. A pint of pub beer is famously more expensive in the south of England than the north, but supermarket beer prices are very similar.

This may be treated as anecdotal evidence in favour of the Balassa—Samuelson hypothesis, since supermarket beer is an easily transportable, traded good. Although pub beer is transportable, the pub itself is not. The BS-hypothesis explanation for the price differentials is that the 'productivity' of pub employees in pints served per hour is more uniform than the 'productivity' in foreign currency earned per year of people working in the dominant tradable sector in each region of the country financial services in the south of England, manufacturing in the north.

Although the employees of southern pubs are not significantly more productive than their counterparts in the north, southern pubs must pay wages comparable to those offered by other southern firms in order to keep their staff. This results in southern pubs incurring a higher labour cost per pint served.

Empirical evidence on the Balassa—Samuelson effect[ edit ] Evidence for the Penn effect is well established in today's world and is readily observable when traveling internationally. However, the Balassa—Samuelson BS hypothesis implies that countries with rapidly expanding economies should tend to have more rapidly appreciating exchange rates for instance the Four Asian Tigers ; conventional econometric tests have resulted with mixed findings for the predictions of the BS effect.

In total, since it was re discovered in , according to Tica and Druzic [2] the HBS theory "has been tested 60 times in 98 countries in time series or panel analyses and in countries in cross-country analyses. In these analyzed estimates, country specific HBS coefficients have been estimated times in total, and at least once for 65 different countries". Also, one should have in mind that a lot of papers have been published since then.

Over time, the testing of the HBS model has evolved quite dramatically. Panel data and time series techniques have crowded out old cross-section tests, demand side and terms of trade variables have emerged as explanatory variables, new econometric methodologies have replaced old ones, and recent improvements with endogenous tradability have provided direction for future researchers.

Consensus has been reached on the testing of internal and external HBS effects vis a vis a numeraire country with a strong reservation against the purchasing power parity assumption in the tradable sector.

Analysis of empirical data shows that the vast majority of the evidence supports the HBS model. A deeper analysis of the empirical evidence shows that the strength of the results is strongly influenced by the nature of the tests and set of countries analyzed.

Almost all cross-section tests confirm the model, while panel data results confirm the model for the majority of countries included in the tests.

These correlations are present in all subsectors, although the values are somewhat lower in the non-tradable subsectors. Third, our approach also allows us to shed some light on whether differences in the results stem from the choice of the productivity measure TFP or LP , the estimation period or the choice of the data set. Finally, two other macroeconomic variables, the real interest rate RI and the population growth rate DPOP , are taken into account.

This increase affects the relative role of tradable and non-tradable goods negatively because certain spending tends to fall more formally on non-tradables. The heartbeat of this paper is very as follows.

Gubler and Sax provide a static general-equilibrium framework with skill-based technological change SBTC , in which higher productivity in the tradable sector can lower wages, which in turn leads to lower prices of non-tradables and thus to a depreciation of the real exchange rate. De Gregorio and Wolf show theoretically that an increase in government spending causes the equilibrium real exchange rate to appreciate if capital mobility across countries is restricted. This alone may shift the consumer price index , and might make the non-trade sector look relatively less productive than it had been when demand was lower; if service quality rather than quantity follows diminishing returns to labour input, a general demand for a higher service quality automatically produces a reduction in per-capita productivity. Although the employees of southern pubs are not significantly more productive than their counterparts in the north, southern pubs must pay wages comparable to those offered by other southern firms in order to keep their staff.

These countries then have a current-account surplus. Introduction The Balassa-Samuelson BS hypothesis—stated by both Balassa and Samuelson , with a research precedent in the work of Harrod —is one of the most widespread explanations for structural deviations from purchasing power parity PPP Footnote 1.

Therefore, the RER -deviation exists independent of what happens to the nominal exchange rate which is always 1 for areas sharing the same currency. Developing economies grow by becoming more productive and using land, labor, and capital more efficiently. Overall, we find strong evidence for non-stationary behavior for all variables, with the exception of the population growth rate, DPOP. In contrast, when the relative productivity of non-tradables increases, marginal cost cuts result in a lower price level.

As noted by De Gregorio and Wolf , the average labor productivity increases much more quickly during economic downturns; hence, it is not a reliable indicator of sustainable productivity growth, which can affect the economy in the medium or long term. The BS-hypothesis explanation for the price differentials is that the 'productivity' of pub employees in pints served per hour is more uniform than the 'productivity' in foreign currency earned per year of people working in the dominant tradable sector in each region of the country financial services in the south of England, manufacturing in the north. This paper applies two panel cointegration models to estimate the long-run relationship between the real exchange rate and key explanatory variables, focusing on the effect of the TFP differential between tradables and non-tradables.
