Wskaźniki wyprzedzające dla polskiej gospodarki

This paper concerns leading indicators for Polish economy. It includes the Leading Indicator for whole economy and for its inflation. There are two kinds of leading indexes for whole economy: Leading Index, which consists of such series as new orders, building permits, stock prices and corporate profits. These series reliably lead the coincident index and GDP by several months, thus revealing the direction in which the economy is headed in the future; the other index is the relatively new - Long Leading Index. This index has roughly twice the lead of other leading indexes and provides forecasts of the coincident index and its components as well as GDP by as much as year in advance. Because of short term of observation, not proper or unavailable data, there are no possibilities to prepare long leading index for Polish economy up to this time. For Leading Index i used the quality and quantity series. The quantity series are: money supply (M2), credit liabilities of households, Warsaw stock price index and productivity (deflated value of sold production divided by number of employees). The quality data includes: new orders, financial situation of enterprises, inventories and consumer confidence index. The quality data is easily available and is collected using same methodology throughout the survey. All the data; both quality and quantity are seasonally adjusted using ARIMA X-12, deflated with the base year 1995=100 and standariesed. The regression between my Leading Index and the curve of production, GDP, and my Coincident Index with lead from 2 to 7 months is pretty high and amounts 0,89-0,95. The second leading index for Poland is Leading Index for Inflation. I used such components as: average of unit costs in industry, forecasts of prices, consumer confidence index (this dada is from surveys), real changes in money supply (M2), the value of zloty to dollar. This index represents the main tendency for inflation very well (comparing to CPl curve) but unfortunately it has very short lead - only 2-3 months.
