This glossary provides short, neutral definitions of the core terms used across this site. Definitions are descriptive (not interpretive) and are designed to keep reading smooth and consistent.
The labor force participation rate calculated for a specific age group. It measures the share of individuals within that age group who are either employed or actively seeking work. This allows participation to be examined as a structure across different stages of the life cycle.
An indicator measuring the degree to which a country’s sectoral distribution of labor corresponds to its sectoral distribution of productivity. Higher values indicate closer correspondence between where workers are employed and where value is generated.
A dynamic pattern in which structural productivity gaps across sectors decrease over time, indicating movement toward alignment between labor allocation and productivity.
A method of breaking a change in an aggregate variable into the contributions of its underlying components. In this site, decomposition is used to separate changes into distinct effects, such as participation, unemployment, and interaction effects, allowing the sources of change to be examined explicitly.
A dynamic pattern in which structural productivity gaps widen over time, indicating increasing separation between sectors in terms of productivity.
The number of people engaged in paid work or self-employment. It measures active labor utilization but does not indicate productivity or job quality.
The percentage of the working-age population that is employed. It reflects how much of the potential labor supply is actually used.
The price of one country’s currency expressed in terms of another. It determines how domestic economic values are converted into a common international currency and can fluctuate independently of real production.
The ratio of employed persons to the working-age population. In this project, it is used interchangeably with labor utilization.
A regulatory practice in which authorities allow financially weak or undercapitalized banks to continue operating without immediate resolution. This may involve delaying loss recognition, relaxing capital requirements, or providing liquidity support.
Financial forbearance is often justified during crises as a way to prevent panic, credit contraction, or systemic instability. However, prolonged forbearance can also slow the restructuring of the financial system and delay the reallocation of capital toward more productive firms.
A firm operating at or near the technological and productivity frontier of its sector. Frontier firms typically adopt advanced technologies, management practices, and capital equipment earlier than other firms.
In productivity analysis, the distance between frontier firms and the rest of the economy often indicates the degree of technology diffusion and structural efficiency.
The total monetary value of all final goods and services produced within a country during a given period. It represents the overall scale of economic output and is commonly used to compare the size of economies.
Gross domestic product divided by total population. It expresses average economic output per person and is commonly used as a proxy for income level. It does not reflect income distribution.
Gross domestic product divided by total population and expressed in current U.S. dollars using market exchange rates. It reflects average income measured in international currency terms but is influenced by exchange rate fluctuations.
Gross domestic product divided by total population and adjusted for differences in price levels across countries. It aims to reflect differences in real purchasing power rather than currency market values.
A sustained increase in the general price level over time. Inflation reduces the purchasing power of money and creates differences between nominal and real measures of economic activity.
A residual component in the exact decomposition of changes in labor utilization, capturing the combined effect of simultaneous changes in participation and unemployment.
A measure of how far sectoral relative productivity levels deviate, on average, from the national productivity benchmark. It is used to quantify the degree of structural dispersion across sectors within an economy.
\(D_{L1}=\frac{1}{N}\sum_i |RP_i-1|\)
Where \(RP_i\) denotes the relative productivity of sector \(i\), and \(N\) is the number of sectors considered (typically agriculture, industry, and services). Smaller values indicate that sectoral productivity levels are close to the national average (structural compression), while larger values indicate wider productivity gaps and a higher degree of structural duality.
The total number of people who are either employed or actively seeking employment. It excludes those who are not participating in the labor market.
The percentage of the working-age population that is either employed or actively seeking employment. It indicates how much of the population is engaged in the labor market.
Output produced per unit of labor input. It is commonly measured as GDP or value added divided by the number of workers or hours worked.
A measure of how fully the available labor force is engaged in productive activity, typically reflected in the combined behavior of labor force participation and unemployment.
The share of the working-age population that is employed. It combines labor force participation and employment outcomes into a single measure.
A method of expressing changes in labor utilization as the sum of participation, unemployment, and interaction effects.
A structural identity expressing the employed population ratio as the product of labor force participation and the employment rate within the labor force:
\(E/P = LFPR \times (1 – u)\)
It shows that labor utilization depends on both participation in the labor market and the ability of the labor market to absorb participants into employment.
The distribution of labor force participation across age groups within an economy. Rather than viewing participation as a single aggregate rate, this concept emphasizes how participation is allocated across different stages of life, such as youth, prime working age, and older ages.
Gross domestic product measured at current market prices in a given year. It reflects both changes in quantities produced and changes in prices.
The contribution to changes in labor utilization arising from changes in the labor force participation rate, holding employment conditions constant.
A dynamic pattern in which structural productivity gaps remain relatively stable over time, indicating limited adjustment in the relationship between labor allocation and productivity.
The average level of prices for goods and services in an economy at a given time. Differences in price levels across countries affect the real purchasing power of income.
Individuals typically aged 25–54, representing the central working-age population. Participation rates for this group are often relatively high and stable across countries, making them a useful reference point when comparing participation structures.
Labor-force participation among individuals in the central working-age population,
typically defined as ages 25–54.
Because most people in this age range are strongly attached to the labor market,
prime-age participation is often used to observe the structural core of labor utilization.
The difference in productivity levels between sectors, firms, or countries. It indicates variation in output per worker across economic units.
Total output divided by the number of employed persons. It reflects average output generated by each worker and is often used to compare economic efficiency across countries or sectors.
A method of adjusting monetary values to account for differences in price levels between countries. It estimates how much a common basket of goods and services would cost in each country, allowing more meaningful comparisons of real living standards.
Gross domestic product adjusted for changes in price levels. It reflects changes in the volume of production rather than price movements.
The rate at which real gross domestic product increases over a given period. It measures changes in the volume of economic output after adjusting for inflation.
A measure comparing the productivity of a sector to the economy-wide average productivity. It is used to show whether a sector produces more or less output per worker than the national mean.
\(RP_i=\frac{P_i}{\bar{P}}\)
Where \(P_i\) is the productivity of sector \(i\), and \(\bar{P}\) is the economy-wide average productivity. If \(RP > 1\), the sector is more productive than the national average. If \(RP < 1\), it is less productive than the national average. In this site, relative productivity is used to compare structural differences across agriculture, industry, and services.
A comparison of productivity levels between sectors or between a sector and the overall economy. It expresses how productive one sector is relative to another reference point.
The process through which young people move from education into employment.
This transition may be shaped by education systems, vocational training,
labor-market institutions, part-time employment opportunities,
and broader social expectations regarding work and adulthood.
The proportion of total employment accounted for by a specific economic sector. It describes how labor is distributed across sectors at a given time.
Value added generated within a specific sector divided by the number of workers in that sector. It reflects average output per worker in that sector.
The portion of total value added generated by a specific economic sector, such as agriculture, industry, or services. It describes the sector’s contribution to overall economic output.
A condition in which productivity differences across sectors become smaller over time. In a structurally compressed economy, sectoral productivity levels move closer to the national average, indicating that productivity is more evenly distributed across the economy. Structural compression is associated with stronger diffusion of capital, technology, and organizational practices, as well as smoother labor reallocation between sectors.
A condition in which high-productivity and low-productivity segments persist side by side within the same economy. In a structurally dual economy, some sectors or firms remain far above the national productivity average while others remain persistently below it. Structural duality usually reflects weak diffusion, slow reallocation, segmentation, or the prolonged survival of low-productivity firms. A rich economy may still remain structurally dual if its productivity gains are concentrated in limited parts of the system.
The movement of labor, capital, and economic activity from lower-productivity sectors or firms toward higher-productivity ones. Structural reallocation is one of the main channels through which aggregate productivity can rise over time. When reallocation is smooth, productivity gaps may shrink and the economy may become more structurally compressed. When reallocation is blocked or slow, structural duality may persist.
The long-term shift in the composition of economic activity and employment across sectors, often associated with development and changes in technology or income levels.
The contribution to changes in labor utilization arising from changes in the unemployment rate, holding participation constant.
The percentage of the labor force that is without work but actively seeking employment. It measures labor market slack rather than population size.
The share of the labor force that is not employed but is actively seeking work.
The additional value created by a sector or firm through the production process. It is calculated as output minus the value of intermediate inputs and represents that sector’s direct contribution to GDP.
The portion of the population considered eligible to participate in the labor market, typically defined within a specific age range such as 15 to 64. It represents the potential labor supply, not actual employment.
A bank that is economically weak or effectively insolvent, but continues operating because losses are not fully recognized and resolution is delayed. Such banks may survive through regulatory forbearance, liquidity support, or flexible asset valuation rather than through restored balance-sheet strength.
A zombie bank can preserve short-term financial stability by avoiding immediate failure, but it may also weaken long-term economic dynamism if it continues lending to weak borrowers and slows the reallocation of capital toward more productive firms.
Assets (market value) < Liabilities
Equity < 0
In this site, the term is used analytically rather than rhetorically. It refers to a balance-sheet condition combined with a policy choice, and is closely related to financial forbearance and evergreening.
