The Unassuming Economist

From a NBER paper by Zhiguo He & Wei Wei:

“China’s financial system has been integral to its spectacular economic growth over the past 40 years. We review the recent literature on China’s financial system and its connections to the Chinese economy based on the categories of Aggregate Financing to the Real Economy (AFRE), a broad measure of the nation’s yearly flow of liquidity accounting for unique features of China’s financial system. While early work on China’s financial system emphasizes the state-owned enterprise (SOE) reform, the recent literature explores other more market-based financing channels—including shadow banking—that grew rapidly after 2010 and have become important components of AFRE. These new financing channels are not only intertwined with each other, but more importantly often ultimately tied back to the dominant banking sector in China. Understanding the mechanisms behind these channels and their intrinsic connections is crucial to alleviate capital allocation distortion and mitigate potential systemic financial risk in China.”

From a NBER paper by John H. Cochrane:

“The fiscal theory states that inflation adjusts so that the real value of government debt equals the present value of real primary surpluses. Monetary policy remains important. The central bank can set an interest rate target, which determines the path of expected inflation, while news about the present value of surpluses drives unexpected inflation. I use fiscal theory to interpret historical episodes, including the rise and fall of inflation in the 1970s and 1980s, the long quiet zero bound of the 2010s, and the reemergence of inflation in 2021, as well as to analyze the gold standard, currency pegs, the ends of hyperinflations, currency crashes, and the success of inflation targets. Going forward, fiscal theory warns that inflation will have to be tamed by coordinated monetary and fiscal policy. I thank Erik Hurst, Ed Nelson, Nina Pavcnik, and Timothy Taylor for helpful comments.”

From a NBER paper by Richard Baldwin:

“Globalisation affects the functioning of the macroeconomy. The macroeconomy’s functioning, in turn, conditions the conduct and impact of monetary policy. This is why globalisation matters for central banks. It is also why central bankers should pay attention to the evolution of globalisation. And evolve it has. This paper argues that the future of trade is trade in services – especially trade in intermediate services. Barriers are radically higher and falling radically faster for services versus goods, and, unlike farm and factory goods, there is no capacity constraint when it comes to the export of intermediate services from emerging markets. Undertaking the macroeconomic analysis for services trade that was done in the 2000s for goods trade, however, will require a substantial upgrading of the data available.”

From a NBER paper by Per Krusell & Anthony A. Smith Jr:

“The economic effects of climate change vary across both time and space. To study these effects, this paper builds a global economy-climate model featuring a high degree of geographic resolution. Carbon emissions from the use of energy in production increase the Earth’s (average) temperature and local, or regional, temperatures respond more or less sensitively to this increase. Each of the approximately 19,000 regions makes optimal consumption-savings and energy-use decisions as its climate (or regional temperature) and, consequently, its productivity change over time. The relationship between regional temperature and regional productivity has an inverted U-shape, calibrated so that the high-resolution model replicates estimates of aggregate global damages from global warming. At the global level, then, the high-resolution model nests standard one-region economy-climate models, while at the same time it features realistic spatial variation in climate and economic activity. The central result is that the effects of climate change vary dramatically across space—with many regions gaining while others lose—and the global average effects, while negative, are dwarfed quantitatively by the differences across space. A tax on carbon increases average (global) welfare, but there is a large disparity of views on it across regions, with both winners and losers. Climate change also leads to large increases in global inequality, across both regions and countries. These findings vary little as capital markets range from closed (autarky) to open (free capital mobility).”

From an article in Tribune by Murtaza Syed:

“Mahbub ul Haq taught me all I know about economics that is ultimately worth knowing. In a nation cruelly short of heroes, Mahbub, my first boss, was a shining light. As Chief Economist of the Planning Commission in the 1960s, he punctured the celebrated high growth rates of the Ayub era. He showed an enraptured domestic audience that state resources had been misused to create powerful monopolies that stifled entrepreneurship and only survived because of subsidies. As a result, the benefits of this growth had been hijacked by a handful of families, who controlled the majority of the country’s land and industrial wealth.

Later, as an adviser to World Bank President Robert McNamara, Mahbub launched a frontal assault on the false god of economic growth and its cathedral on earth, the free play of market forces. He pointed out that across the world, too, growth often fails to translate into better lives for ordinary people. Moreover, he argued that the mythical forces of demand and supply do not work when people are shackled by low purchasing power or a handful has monopoly power. To address this, he saw a vital role for the state in kick-starting the process of growth and ensuring it was equitably shared. Through these insights, he pioneered the paradigm of human development, and with it the vastly influential human development index which looks beyond GDP to capture other vital dimensions of human well-being like decent education, good health, political freedom, cultural identity, personal security, community participation, and environmental security.

Mahbub was a man ahead of his time. His eloquence reverberated on the world stage. He emerged as the spokesperson of the developing world, incessantly appealing to the conscience of richer nations. He is missed every day. Today, a quarter century after his untimely passing, his beloved homeland remains mired in desperate poverty and massive inequality. While most of our neighbours have taken off, we remain stuck at a per capita income of a little over $1,000 and every third person lives on less than $3 a day. Almost half our people are illiterate and less than a quarter of our women work.

Much like in Mahbub’s time, the fault still lies in the engines of our growth and the fickleness of our public policies. Our politicians are obsessed with growth at any cost but pull the wrong levers to achieve it time and time again: lazy, short-term stimulus that inevitably leads to painful busts as opposed to the long and winding road of structural reforms that unleashes prolonged growth through higher productivity and innovation. Short-termism associated with political cycles and an unfortunate lack of preparation and imagination among the economic teams of political parties is to blame.

Pakistan today is a country that can barely grow above 4-5% without finding itself hobbled by a current account deficit it cannot finance. Its growth model is too reliant on consumption, which accounts for a staggering 95% of overall output, while investment and exports make up just 15 and 10%, respectively. As a result, the country runs a perennial current account deficit, in stark contrast to the surpluses generated by the high-saving Asian tigers of the 1970s and 1980s.’
