Does the Balassa - Samuelson theory explain the link between relative population growth and purchasing power parity ?

چکیده
Relative population growth affects relative prices through the so-called BalassaSamuelson (BS) mechanism and that in turn impacts PPP. This paper empirically investigates the relationship between PPP exchange rate and relative population growth in a panel of 80 selected countries. Following the Balassa-Samuelson hypothesis this paper argues that relative population growth affects nominal wages that impact price levels and thereby impacts PPP. Using panel cointegration and fully modified ordinary least square (FMOLS) the empirical results show that there is stable relationship between PPP exchange rate and relative population growth in the long run. These empirical findings suggest that population growth have an important role in exchange rate determination through PPP.

The Harrod - Balassa - Samuelson Hypothesis : Real Exchange Rates and their Long - Run Equilibrium
Frictionless, perfectly competitive traded-goods markets justify thinking of purchasing power parity (PPP) as the main driver of exchange rates in the long-run. But differences in the traded/non-traded sectors of economies tend to be persistent and affect movements in local price levels in ways that upset the PPP balance (the underpinning of the Harrod-Balassa-Samuelson hypothesis, HBS). This p...
متن کاملInternational Migration, Segmented Labour Markets and Competitiveness: Amalgamating the Lewis and Balassa-Samuleson Models
We integrate three hitherto unconnected strands of economic theory; Lewis’ dual economy model, the Balassa-Samuelson model and, segmented labour market theory. With our hybrid model we investigate the implications of migration with labour market segmentation for an economy’s internal competitiveness, where migrants are concentrated in the secondary labour market and this segment supplies unskil...
متن کاملBig Mac parity, income, and trade
Nontraded inputs account for the lion's share of a Big Mac price (Ong 1997, Parsley and Wei 2003). Major departures from Big Mac PPP may then be explained by the Balassa−Samuelson income differences effect, as shown e.g. by Click (1996). But it has been argued that Click's result is not robust to changing estimation methods, sample of countries, and time period (Fujiki and Kitamura 2003). Here ...
متن کاملReal currency appreciation in accession countries: Balassa-Samuelson and investment demand
The Balassa-Samuelson effect is usually seen as the prime explanation of the continuous real appreciation of central and east European (CEE) transition countries' currencies against their western counterparts. The response of a small country's real exchange rate to various shocks is derived in a simple model. It is shown that productivity shocks work not only through a Balassa-type supply chann...
متن کاملThe Price of Development: the Penn-Balassa-Samuelson effect revisited∗
The Penn-Balassa-Samuelson effect is the stylized fact about the positive correlation between cross-country price level and per-capita income. This paper provides evidence that the price-income relation is actually non-linear and turns negative among low income countries. The result is robust along both cross-section and panel dimensions. Additional robustness checks show that biases in PPP est...
