As such, running the regression can result in differing coefficients that are used to solve for the change in unemployment, based on how the economy grew. It all depends on the time periods used and inputs, which are historical GDP and employment data. Below is an example of an Okun's law regression:. The law has indeed evolved over time to fit the current economic climate and employment trends. As with any law in economics, science, or any discipline, it is important to determine if it holds true under varying conditions and over time.
Okun also analyzed the gap between potential economic output and the actual output rate in the economy. It settled on a more dynamic version, leaving options for variables to be left out or added, depending on the levels of current and historical economic growth. Despite the fact that there are in reality many moving parts to the relationship between unemployment and economic growth, there does appear to be empirical support for the law.
The Federal Reserve Bank of St. For instance, since it has been studied, it has been known to shift over time and be impacted by more unusual economic climates, including jobless recoveries and the financial crisis. Because of the complexity of the inputs, the different time periods that can be used, and the basic uncertainty that goes with running economic regressions, analysis can become quite complex.

Why is the unemployment rate never zero? Even when the U. Moreover, the discussion earlier in this chapter pointed out that unemployment rates in many European countries like Italy, France, and Germany have often been remarkably high at various times in the last few decades. Why does some level of unemployment persist even when economies are growing strongly? Why are unemployment rates continually higher in certain economies, through good economic years and bad?
Economists have a term to describe the remaining level of unemployment that occurs even when the economy is healthy: it is called the natural rate of unemployment. It is not a physical and unchanging law of nature. These forces include the usual pattern of companies expanding and contracting their workforces in a dynamic economy, social and economic forces that affect the labor market, or public policies that affect either the eagerness of people to work or the willingness of businesses to hire.
Conversely, other companies will be doing very well for just the opposite reasons and looking to hire more employees. In a perfect world, all of those who lost jobs would immediately find new ones. But in the real world, even if the number of job seekers is equal to the number of job vacancies, it takes time to find out about new jobs, to interview and figure out if the new job is a good match, or perhaps to sell a house and buy another in proximity to a new job.
The unemployment that occurs in the meantime, as workers move between jobs, is called frictional unemployment. Frictional unemployment is not inherently a bad thing. It takes time on part of both the employer and the individual to match those looking for employment with the correct job openings.
For individuals and companies to be successful and productive, you want people to find the job for which they are best suited, not just the first job offered.
But in periods of economic growth, these destroyed jobs are counterbalanced for the economy as a whole by a larger number of jobs created. In , for example, there were typically about 7. Even though about two-thirds of those unemployed people found a job in 14 weeks or fewer, the unemployment rate did not change much during the year, because those who found new jobs were largely offset by others who lost jobs. Of course, it would be preferable if people who were losing jobs could immediately and easily move into the new jobs being created, but in the real world, that is not possible.
Someone who is laid off by a textile mill in South Carolina cannot turn around and immediately start working for a textile mill in California. Instead, the adjustment process happens in ripples. Some people find new jobs near their old ones, while others find that they must move to new locations. Some people can do a very similar job with a different company, while others must start new career paths.
Some people may be near retirement and decide to look only for part-time work, while others want an employer that offers a long-term career path. The frictional unemployment that results from people moving between jobs in a dynamic economy may account for one to two percentage points of total unemployment. The level of frictional unemployment will depend on how easy it is for workers to learn about alternative jobs, which may reflect the ease of communications about job prospects in the economy.
The extent of frictional unemployment will also depend to some extent on how willing people are to move to new areas to find jobs—which in turn may depend on history and culture. Frictional unemployment and the natural rate of unemployment also seem to depend on the age distribution of the population. Figure 2 from Patterns of Unemployment b showed that unemployment rates are typically lower for people between 25—54 years of age than they are for those who are either younger or older.
But some proportion of those who are under 30 may still be trying out jobs and life options and some proportion of those over 55 are eyeing retirement.
In both cases, the relatively young or old tend to worry less about unemployment than those in-between, and their periods of frictional unemployment may be longer as a result.
Thus, a society with a relatively high proportion of relatively young or old workers will tend to have a higher unemployment rate than a society with a higher proportion of its workers in middle age. Another factor that influences the natural rate of unemployment is the amount of structural unemployment. The structurally unemployed are individuals who have no jobs because they lack skills valued by the labor market, either because demand has shifted away from the skills they do have, or because they never learned any skills.
An example of the former would be the unemployment among aerospace engineers after the U. An example of the latter would be high school dropouts. Some people worry that technology causes structural unemployment.
In the past, new technologies have put lower skilled employees out of work, but at the same time they create demand for higher skilled workers to use the new technologies. Education seems to be the key in minimizing the amount of structural unemployment. Individuals who have degrees can be retrained if they become structurally unemployed. For people with no skills and little education, that option is more limited. The natural unemployment rate is related to two other important concepts: full employment and potential real GDP.
The economy is considered to be at full employment when the actual unemployment rate is equal to the natural unemployment. By contrast, when the economy is below full employment, the unemployment rate is greater than the natural unemployment rate and real GDP is less than potential.
Finally, when the economy above full employment, then the unemployment rate is less than the natural unemployment rate and real GDP is greater than potential. Operating above potential is only possible for a short while, since it is analogous to all workers working overtime.
Unexpected shifts in productivity can have a powerful effect on the natural rate of unemployment. Over time, the level of wages in an economy will be determined by the productivity of workers. After all, if a business paid workers more than could be justified by their productivity, the business will ultimately lose money and go bankrupt.
Conversely, if a business tries to pay workers less than their productivity then, in a competitive labor market, other businesses will find it worthwhile to hire away those workers and pay them more. However, adjustments of wages to productivity levels will not happen quickly or smoothly. Wages are typically reviewed only once or twice a year. In many modern jobs, it is difficult to measure productivity at the individual level.
For example, how precisely would one measure the quantity produced by an accountant who is one of many people working in the tax department of a large corporation? However, when productivity changes unexpectedly, it can affect the natural rate of unemployment for a time.
The U. In the s, productivity growth slowed down unexpectedly as discussed in Economic Growth. For example, output per hour of U. Figure 1 a illustrates the situation where the demand for labor—that is, the quantity of labor that business is willing to hire at any given wage—has been shifting out a little each year because of rising productivity, from D 0 to D 1 to D 2.
This study shows that the Okun law works very poorly for Turkey. The negative-directional regression line obtained in this study using regression analysis revealed the existence of an inverse relationship between the change in unemployment rate and the growth rate.
However growth has an impact on unemployment it must be at least 4. It is seen that similar results have been reached in many different studies on Turkey. These calculations indicate that growth in the period of expansion of the conjuncture in particular had very low effects on employment, and hence the presence of non-employment growth. Another important finding obtained in these studies is that the relationship of Okun in the Turkish economy has an asymmetric structure, that is the effect of reducing unemployment during the expansion period of real output and the increasing unemployment during the contraction period are not same [ 3 ].
When the relationship between the growth rate and the unemployment rate are examined in — period in Turkey it is observed that there is an inverse relationship between growth and unemployment, especially during crisis periods. The unemployment rate reached high levels in , and , and in later years in some periods it began to decline, albeit lagging.
Similarly, with the negative growth conditions caused by the foreign exchange crisis that took place in , unemployment started to rise and reached its highest value in with On the other hand, the impact of the cyclical revival in the economy on unemployment remained relatively weak. It can be said that the decrease in the unemployment rate remained extremely limited in , when the growth rate was the highest in the period studied. In the period of expansion that took place in and , unemployment did not decrease, but rather started to increase Figure 2.
Relationship between growth and unemployment rate — Despite the high economic growth rates achieved in Turkey in recent years, this performance is not reflected in unemployment rates to the same extent, causing controversy.
An economic growth model that depends on consumption-based foreign capital movements that do not provide employment is not sustainable. Considering the presence of rapid population growth and a demographic structure with a young population, it is of great importance to develop an economic growth model with policies based on production, providing employment, focused on high value added products and reducing external dependence [ 17 ].
The current account deficit is less than the amount paid for goods produced and sold abroad to be consumed domestically, indicating that a country is making negative savings [ 20 ]. The relationship between the current account deficit and growth can be two-way relationship. Firstly the country with insufficient savings ratio or negative savings, the current account deficit can affect growth as investment spending is financed through the use of external savings.
Second, as if income growth will increase demand for imported goods, the growth current account deficit may affect growth or may occur as a result of the growth rate itself. The effect of the current account deficit on the growth rate is explained by providing investments with foreign savings if domestic savings are insufficient.
It can be stated as follows if the savings are insufficient in an economy, investments are financed by borrowing of Foreign World Savings. In this context, as emphasized in both development economics and growth models, the source of growth is investment and the source of investment is savings ratio. If domestic savings are insufficient, it means that the difference can be met by using foreign sector savings and the current account deficit.
The current account reflects the relationship between the financial markets and the goods and services markets in an economy. In the balance of payments, by definition, the current account deficit should be financed by capital account. In other words, the current account deficit may only be possible if necessary financing is provided in the capital account in the balance of payments.
International flows of goods and capital are two sides of the coin and this can be explained by the national income accounting authority as follows [ 21 ]:. This identification shows the components of National Income Y , under the assumption of equivalence of public revenues and expenses. Total revenue equals household consumption expenditures C , private sector investment expenditures and the difference between exports X and imports M , i. When necessary adjustments are made here, it can be shown that net exports or the current account balance in a broad sense are equal to the domestic savings investment difference.
Within the framework of this identification, for example, a study covering the s for the United States concluded that the current account deficit could be explained by the lack of savings. In other words, the level of domestic investment is being supported by flows of foreign saving. The study also emphasizes that external savings flows are equal to the negative value of the current account balance [ 22 ].
The many studies similarly have found that the current account deficit affects the growth rate in Turkey as well. For example, changes in the current account deficit were shown to affect economic growth using the structured VAR method by evaluating the quarterly data in — [ 23 ].
The relationship between the current account deficit and growth in Turkey is closely related to the need for Energy oil , investment goods and intermediate imports, as well as the insufficient savings rate. The realization of investments and therefore growth is linked to the current account deficit through the increase in imports.
The consumption expenditures depend mainly on income in the Keynesian approach. Since income growth will affect demand for both domestic and imported goods, it will put a negative pressure on the current account. Thus, in this case, the rate of growth is the independent variable and the current account is the dependent variable, which varies accordingly. The relationship between these two variables is oriented from growth rate to current account balance.
The import expenditure represented by M is an increasing function of income in the equality 6. The volume of imports consists of two components such as autonomous and revenue-dependent in the Keynesian model. Hence the total amount of imports varies in the right direction with income depending on the marginal import trend considered constant [ 24 ].
İt is observed that the mutual causality relationship is towards growth to current account deficit. Figure 3 shows the ratio of the current account to GDP ratio and the growth rate in Turkey over the last 20 years. In the period examined, it is observed that the current account deficit increases during the expansion process and the current account deficit decreases during the contraction periods in Turkey.
In addition, the current account balance has been continuously negative except the years and Similar to when the growth ratio reached its highest value Source: OECD. To summarize it is observed that while growth accelerated when the current account balance in Turkey gave a deficit.
The growth slowed when the current account balance gave a surplus. In this context, the ratio of the current account deficit to GDP was 4. In the same period, the growth rate started to decrease and reached 0. In this study, the degree of stationarity of series are found with Dickey Fuller and Ng -Perron methods. Between series interaction are measured with classic [ 25 ] causality test, [ 26 ] were analyzed by symmetric latent causality test and [ 27 ] asymmetric latent causality test methods.
While [ 27 ] are developing symmetric and asymmetric implicit causality tests, [ 25 ] suggested the analysis which negative and positive shocks can be separated for the cointegration analysis with using the cumulative totals of these shocks. Firstly these series are divided into positive and negative shocks before these causality tests. If causality relationships between two series such as y 1 t and y 2 t series,.
Other models will be helping one by one for each dependent variable with lagged independent other variables. When null hypothesis rejected that means there is causality for each taken dependent variable to independent variables. They [ 26 ] refer to this causality analysis performed between the same types of shocks, [ 27 ] named this causality test asymmetric causality test performed between different types of shocks. In the study, Unit Root perron test [ 28 ] was performed and the findings were presented in Table 1 below.
Ng and Perron unit root test results [ 28 ]. The I 1 all models have trend and constant. It was examined by the method of [ 28 ]. Table 1 was observed that all of the series were not stationary at level as I 0 but when the first differences were taken all variables became stationary as I 1. After the determination of the degree of the level stationary of variables will be used for Granger causality test.
In the analysis, causality relationships between the series were first examined by [ 29 ] method. The first differences of the series were used for Granger causality and the results obtained are presented in Table 2.
Table 1 results show there is a strong one-way causality relationship between Inflation and Economic growth. Inflation rates are also directly affects the higher economic growth rate in Turkey. The import of the raw materials and semi-finished materials are needed during the production effects the economy. Table 3 obtained the hidden causality test relationships results between the all variables which belong to [ 26 ].
We take the positive and negative shocks which refers different effect to causality between each other. The symmetric causality test shows the same shocks effect how affect the causality.
The two way causality with unemployment and inflation under the positive shocks effect. There is a mutual causal relationship between growth and unemployment under the positive shock situation. The inflation causes the growth when they are affected negative shock. There is a one way causality growth to inflation.
