690-488: A country's wealth or income distribution deviates from an equal distribution. The Gini coefficient is usually defined mathematically based on the Lorenz curve , which plots the proportion of the total income of the population (y-axis) that is cumulatively earned by the bottom x of the population (see diagram). The line at 45 degrees thus represents perfect equality of incomes. The Gini coefficient can then be thought of as
805-502: A country. The Gini coefficient on disposable income—sometimes referred to as the after-tax Gini coefficient—is calculated on income after taxes and transfers. It measures inequality in income after considering the effect of taxes and social spending already in place in a country.

The Supreme Council included two other members: General Guillermo Durán Arcentales and General Luis Pintado. The civil society more and more insistently called for democratic elections. Colonel Richelieu Levoyer , Government Minister, proposed and implemented
8740-425: The government restored fuel subsidies and withdrew an austerity package, which ended nearly two weeks of protests. In the 11 April 2021 election , conservative former banker Guillermo Lasso took 52.4% of the vote, compared to 47.6% for left-wing economist Andrés Aráuz , who was supported by exiled former president Correa. Lasso had finished second in the 2013 and 2017 presidential elections. On 24 May 2021, Lasso
8855-576: The government waived the right to tax increases in raw material prices and foreign exchange repatriations. In October 2018, Moreno cut diplomatic relations with the Maduro administration of Venezuela, a close ally of Correa. The relations with the United States improved significantly under Moreno. In June 2019, Ecuador agreed to allow US military planes to operate from an airport on the Galapagos Islands. In February 2020, his visit to Washington
8970-435: The greater the average deviation, the greater the inequality. Based on these observations the inequality indices have this common form: where p j weights the units by their population share, and f ( r j ) is a function of the deviation of each unit's r j from 1, the point of equality. The insight of this generalized inequality index is that inequality indices differ because they employ different functions of
9085-410: The highland Andes mountains, where life was more sedentary, groups of tribes cooperated and formed villages; thus the first nations based on agricultural resources and the domestication of animals formed. Eventually, through wars and marriage alliances of their leaders , groups of nations formed confederations. When the Incas arrived, they found that these confederations were so developed that it took
9200-436: The integration is taken from minus infinity to plus infinity.) The Gini coefficient may be expressed in terms of the quantile function Q ( F ) (inverse of the cumulative distribution function: Q(F(x)) = x) Since the Gini coefficient is independent of scale , if the distribution function can be expressed in the form f(x,φ,a,b,c...) where φ is a scale factor and a, b, c... are dimensionless parameters, then
9315-506: The intention of using them as springboards to occupy the independent city of Guayaquil and then liberate the rest of the Audiencia de Quito (Ecuador). It was common knowledge among officers of the liberation army from the south that their leader San Martín wished to liberate present-day Ecuador and add it to the future republic of Peru, since it had been part of the Inca Empire before the Spaniards conquered it. However, Bolívar 's intention
9430-484: The labour code. Ecuador also left the left-wing Bolivarian Alliance for the Americas (Alba) in August 2018. The Productive Development Act introduced an austerity policy, and reduced the previous development and redistribution policies. Regarding taxes, the authorities aimed to "encourage the return of investors" by granting amnesty to fraudsters and proposing measures to reduce tax rates for large companies . In addition,

9660-461: The lowest and Italy the highest. The Gini coefficient (after-taxes and transfers) for a total population ranged between 0.25 and 0.48, with Denmark the lowest and Mexico the highest. For the United States, the country with the largest population among OECD countries, the pre-tax Gini index was 0.49, and the after-tax Gini index was 0.38 in 2008–2009. The OECD average for total populations in OECD countries
9775-424: The measurement of concentration and variability of characters in 1914. Here, he presented the concentration ratio , which further developed in the Gini coefficient used today. Secondly, Gini observed that his proposed ratio can be also achieved by improving methods already introduced by Lorenz, Chatelain, or Séailles. In 1915, Gaetano Pietra introduced a geometrical interpretation between Gini's proposed ratio and
9890-588: The missionary villages in the Mainas or Maynas region, which it began calling Loreto, with its capital in Iquitos . During its negotiations with Brazil, Peru claimed Amazonian Basin territories up to Caqueta River in the north and toward the Andes Mountain range. Colombia protested stating that its claims extended south toward the Napo and Amazon Rivers. Ecuador protested that it claimed the Amazon Basin between
10005-406: The most equal possible society in which every person receives the same income ( G = 0 ), and the most unequal society (with N individuals) where a single person receives 100% of the total income and the remaining N − 1 people receive none ( G = 1 − 1/ N ). A simple case assumes just two levels of income, low and high. If the high income group is a proportion u of the population and earns
10120-469: The need to divide by N² instead. FAO explains another version of the formula. The Gini coefficient and other standard inequality indices reduce to a common form. Perfect equality—the absence of inequality—exists when and only when the inequality ratio, r j = x j / x ¯ {\displaystyle r_{j}=x_{j}/{\overline {x}}} , equals 1 for all j units in some population (for example, there
10235-541: The newly discovered Real Cedula of 1802, by which Peru claims the King of Spain had transferred these lands from the Viceroyalty of New Granada to the Viceroyalty of Peru. During colonial times this was to halt the ever-expanding Portuguese settlements into Spanish domains, which were left vacant and in disorder after the expulsion of Jesuit missionaries from their bases along the Amazon Basin. Ecuador countered by labeling
10350-558: The other branches of government give the president very little political capital, as illustrated by the most recent removal of President Lucio Gutiérrez from office by Congress in April 2005. Vice President Alfredo Palacio took his place In the election of 2006 , Rafael Correa gained the presidency. In January 2007, several left-wing political leaders of Latin America, his future allies, attended his swearing-in ceremony. Endorsed in
10465-589: The people of the highland Andes developed a sedentary agricultural way of life; and peoples of the Amazon basin relied on hunting and gathering; in some cases, this is combined with agriculture and arboriculture . Many civilizations arose in Ecuador, such as the Valdivia Culture and Machalilla Culture on the coast, the Quitus (near present-day Quito), and the Cañari (near present-day Cuenca ). In
10580-432: The population Gini coefficient, should be reported. These can be calculated using bootstrap techniques, mathematically complicated and computationally demanding even in an era of fast computers. Economist Tomson Ogwang made the process more efficient by setting up a "trick regression model" in which respective income variables in the sample are ranked, with the lowest income being allocated rank 1. The model then expresses
10695-433: The power of the clergy and the conservative land owners. This liberal wing retained power until the military "Julian Revolution" of 1925. The 1930s and 1940s were marked by instability and emergence of populist politicians, such as five-time President José María Velasco Ibarra . Brasilia Presidential Act After Ecuador's separation from Colombia on 13 May 1830, its first President, General Juan José Flores , laid claim to
10810-408: The rank (dependent variable) as the sum of a constant A and a normal error term whose variance is inversely proportional to y k : Thus, G can be expressed as a function of the weighted least squares estimate of the constant A and that this can be used to speed up the calculation of the jackknife estimate for the standard error. Economist David Giles argued that the standard error of
10925-499: The ratio between the area of observed concentration and maximum concentration. This altered version of Gini coefficient became the most commonly used inequality index in upcoming years. According to data from OECD , Gini coefficient was first officially used country-wide in Canada in the 1970s. Canadian index of income inequality ranged from 0.303 to 0.284 from 1976 to the end of 1980s. OECD started to publish more countries’ data since
11040-428: The ratio of the area that lies between the line of equality and the Lorenz curve (marked A in the diagram) over the total area under the line of equality (marked A and B in the diagram); i.e., G = A /( A + B ) . If there are no negative incomes, it is also equal to 2 A and 1 − 2 B due to the fact that A + B = 0.5 . Assuming non-negative income or wealth for all, the Gini coefficient's theoretical range
11155-417: The revolution of Trujillo by the Peruvian occupying force, had the whole region swear allegiance to the new Peruvian flag and incorporated itself into Peru. Gran Colombia had always protested Peru for the return of Jaén and Tumbes for almost a decade, then finally Bolivar after long and futile discussion over the return of Jaén, Tumbes, and part of Mainas, declared war. President and General José de La Mar , who
11270-549: The richest person receives a rank of 1 and the poorest a rank of N . This effectively gives higher weight to poorer people in the income distribution, which allows the Gini to meet the Transfer Principle . Note that the Jasso-Deaton formula rescales the coefficient so that its value is one if all the X i {\displaystyle X_{i}} are zero except one. Note however Allison's reply on
11385-604: The sample Gini coefficient is a consistent estimator of the population Gini coefficient, but is not in general unbiased . In simplified form: There does not exist a sample statistic that is always an unbiased estimator of the population Gini coefficient. For a discrete probability distribution with probability mass function f ( y i ) , {\displaystyle f(y_{i}),} i = 1 , … , n {\displaystyle i=1,\ldots ,n} , where f ( y i ) {\displaystyle f(y_{i})}
11500-717: The signing of the Treaty of Guayaquil in September 1829, whereby Peru and its Congress recognized Gran Colombian rights over Tumbes, Jaén, and Maynas. Through meetings between Peru and Gran Colombia, the border was set as Tumbes river in the west, and in the east, the Maranon and Amazon rivers were to be followed toward Brazil as the most natural borders between them. According to the peace negotiations Peru agreed to return Guayaquil, Tumbez, and Jaén; despite this, Peru returned Guayaquil, but failed to return Tumbes and Jaén, alleging that it
11615-414: The start of the 21st century. Central European countries Slovenia , Czechia , and Slovakia have had the lowest inequality index out of all OECD countries ever since the 2000s. Scandinavian countries also frequently appeared at the top of the list of equality in the last decades. The Gini coefficient is an index for the degree of inequality in the distribution of income/wealth, used to estimate how far
11730-570: The territory that had belonged to the Real Audiencia of Quito , also referred to as the Presidencia of Quito. He supported his claims with Spanish Royal decrees, or real cedulas , that delineated the borders of Spain's former overseas colonies. In the case of Ecuador, Flores based Ecuador's de jure claims on the Real Cedulas of 1563, 1739, and 1740; with modifications in the Amazon Basin and Andes Mountains that were introduced through
11845-445: The value of B can be found by integration : The Gini coefficient can also be calculated directly from the cumulative distribution function of the distribution F ( y ). Defining μ as the mean of the distribution, and specifying that F ( y ) is zero for all negative values, the Gini coefficient is given by: The latter result comes from integration by parts . (Note that this formula can be applied when there are negative values if
11960-632: The walls of Quito referring to Peru as the " Cain de Latinoamérica ", a reference to the murder of Abel by his brother Cain in the Book of Genesis . Ecuador and Peru signed the Brasilia Presidential Act peace agreement on 26 October 1998, which ended hostilities, and effectively put an end to the Western Hemisphere's longest running territorial dispute. The Guarantors of the Rio Protocol (Argentina, Brazil, Chile, and
12075-572: The wealth Gini coefficient is at least 49%. In some cases, this equation can be applied to calculate the Gini coefficient without direct reference to the Lorenz curve . For example, (taking y to indicate the income or wealth of a person or household): The Gini coefficient can also be considered as half the relative mean absolute difference . For a random sample S with values y 1 ≤ y 2 ≤ ⋯ ≤ y n {\displaystyle y_{1}\leq y_{2}\leq \cdots \leq y_{n}} ,
12190-441: The work of American economist Max Lorenz , Gini proposed that the difference between the hypothetical straight line depicting perfect equality, and the actual line depicting people's incomes, be used as a measure of inequality. In this paper, he introduced the concept of simple mean difference as a measure of variability. He then applied the simple mean difference of observed variables to income and wealth inequality in his work On
12305-623: The world to become listed sites. The Rio Protocol failed to precisely resolve the border along a little river in the remote Cordillera del Cóndor region in southern Ecuador. This caused a long-simmering dispute between Ecuador and Peru, which ultimately led to fighting between the two countries; first a border skirmish in January–February 1981 known as the Paquisha Incident , and ultimately full-scale warfare in January 1995 where
12420-524: Was 0.46 for the pre-tax income Gini index and 0.31 for the after-tax income Gini index. Taxes and social spending that were in place in 2008–2009 period in OECD countries significantly lowered effective income inequality, and in general, "European countries—especially Nordic and Continental welfare states —achieve lower levels of income inequality than other countries." Using the Gini can help quantify differences in welfare and compensation policies and philosophies. However, it should be borne in mind that
12535-512: Was born in Ecuador, believing his opportunity had come to annex the District of Ecuador to Peru, personally, with a Peruvian force, invaded and occupied Guayaquil and a few cities in the Loja region of southern Ecuador on 28 November 1828. The war ended when an outnumbered southern Gran Colombian army at Battle of Tarqui on 27 February 1829, led by Antonio José de Sucre , defeated the Peruvian invasion force led by President La Mar. This defeat led to
12650-584: Was not obligated to follow the agreements, since the Gran Colombia ceased to exist when it divided itself into three different nations – Ecuador, Colombia, and Venezuela. The Central District of the Gran Colombia, known as Cundinamarca or New Granada (modern Colombia) with its capital in Bogota, did not recognize the separation of the Southern District of the Gran Colombia, with its capital in Quito, from
12765-595: Was signed by which the Department of Cauca was turned over to New Granada (modern Colombia), the government of Bogotá recognized Ecuador as an independent country and the border was to follow the Ley de División Territorial de la República de Colombia (Law of the Division of Territory of the Gran Colombia) passed on 25 June 1824. This law set the border at the river Carchi and the eastern border that stretched to Brazil at
12880-505: Was studied by Alexander von Humboldt , when he visited the area in 1801–1802. After nearly 300 years of Spanish rule, Quito still remained small with a population of 10,000 people. On 10 August 1809, the city's criollos called for independence from Spain (first among the peoples of Latin America). They were led by Juan Pío Montúfar, Quiroga, Salinas, and Bishop Cuero y Caicedo. Quito's nickname, " Luz de América " ("Light of America"),
12995-507: Was sworn in, becoming the country's first right-wing leader in 14 years. Lasso's party CREO Movement, and its ally the Social Christian Party (PSC) won only 31 parliamentary seats out of 137, while Aráuz's Union for Hope (UNES) won 49 seats, which meant Lasso needed support from the Izquierda Democrática and the indigenist Pachakutik parties to push through his legislative agenda. Gini coefficient In economics ,
13110-408: Was the first meeting between an Ecuadorian and U.S. president in 17 years. A series of protests began on 3 October 2019 against the end of fuel subsidies and austerity measures adopted by Moreno. On 10 October, protesters overran Quito, the capital, causing the Government of Ecuador to relocate temporarily to Guayaquil . The government eventually returned to Quito in 2019. On 14 October 2019,
13225-489: Was to form a new republic known as the Gran Colombia , out of the liberated Spanish territory of New Granada which consisted of Colombia, Venezuela, and Ecuador. San Martín's plans were thwarted when Bolívar, descended from the Andes mountains and occupied Guayaquil; they also annexed the newly liberated Audiencia de Quito to the Republic of Gran Colombia. In the south, Ecuador had claims to a small piece of land beside
