The government in Pakistan under under Nawaz Sharif’s party had the best performance in managing the economy over the past three decades compared with rivals, according to an analysis by Bloomberg Economics.

Using a misery index for Pakistan, which combines the unemployment and inflation rates, Bloomberg Economics found that Nawaz Sharif’s Pakistan Muslim League scored better than Imran Khan’s Pakistan Tehreek-e-Insaf and the Pakistan Peoples Party of Asif Ali Zardari and Bilawal Bhutto Zardari.

The analysis was done by using a misery index which informally measures an economy's state by adding its inflation and unemployment rate.

"Bloomberg Economics used an average of the index values over the respective years when each of the major political parties ruled the country since 1990. A higher value indicates more economic hardship for citizens," said the analysis.

According to Bloomberg, Nawaz Sharif looks ready to take power after the general elections slated for February 8 for the fourth time, with Imran Khan being incarcerated and stuck in a quagmire of legal cases.

However, despite being in jail, Khan is still the most popular politician in Pakistan with an approval rating of 57%, as per a Gallup opinion poll. Meanwhile, Nawaz's popularity increased from 36% to 52% in the past six months.

“The public may be giving Sharif the benefit of the doubt,” Ankur Shukla of Bloomberg Economics wrote in the report, adding that the "road ahead won’t be easy for any party that wins the election", considering the high inflation and unemployment rate.

The inflation rate in Pakistan is close to 30% while the rupee performed as the worst in Asia last year with declining foreign exchange reserves.

Furthermore, the country is seeking a financial bailout from the International Monetary Fund (IMF) and the upcoming government will have to implement policies — withdrawing subsidies and raising taxes — that will be unpopular with voters.

The global lender also expects the economy to grow by 2% in the fiscal year.
