Recent signs of economic strength, together with a pair of key  departures from the Federal Reserve Board, may have shortened the odds on   an interest rate hike by the central bank.   
"The chances are better than many people may think, probably about 50-  50," for a rate increase when the Fed's monetary policymakers meet in two   weeks, said Robert A. Brusca, chief economist at Nikko Securities Co., New   York.     
  
"The Fed has to be concerned about some of the trends it sees," he said.  In particular, recent job market data "point to nothing but growth, more   growth, and maybe some more inflation."   
A newer member of the Fed's board of governors, Laurence H. Meyer,  appeared to express concern during an interview last Thursday. He cautioned   that the Fed must avoid "complacency" about incipient inflation.   
  
Meanwhile Janet L. Yellen and Lawrence B. Lindsey are set to leave. Both  have been "among the more moderate voices" on monetary policy, said Mr.   Brusca, and their departures thus probably move the Fed "a step closer" to   hiking rates.     
Fed Chairman Alan Greenspan, who deflected rate hike pressure brought by  district Fed bank presidents at several open market committee meetings last   summer, according to the Fed's own minutes, now will face similar pressures   without his previous allies.     
Mr. Greenspan himself has offered few clues recently about his views on  yearend economic developments. The committee next meets Feb. 3-4. 
  
Another economist, Jonathan Basile of HSBC Markets, New York, put the  probability of a February rate hike at 55% to 45%. "The interest rate   debate is back with a vengeance," he said.   
The reason is not the higher-than-expected 262,000 increase in nonfarm  payrolls in December. If the atypical 31,000 rise in government payrolls   last month were excluded, job growth was not higher than expected, he said.   
The focus of the debate is the six-cent jump in hourly earnings, coming  after a nine-cent rise in November. "After having stabilized over the   summer in a 3%-3.5% range, the year-over-year rate of earnings growth has   now hit 3.8%, a six-year high," he said.     
The November and December increases may be linked to the October  increase in the minimum wage, Mr. Basile said. 
  
"January's data will be the acid test," he said. "If earnings jump  again, it will be hard to argue that the minimum wage is the cause. The   balance will then swing, and rates will rise."   
But labor market trends are not the only issue likely to get major  scrutiny by the central bank, he said. 
"It is becoming harder to discount completely the idea that the Fed may  be forced into action by the sustained increase in energy prices over the   past few months," the economist said.   
"With no end in sight to the pressure from low inventories, cold  weather, and supply uncertainties, the divergence between headline and core   inflation is set to widen further," he said.   
Economists refer to the raw consumer price index reported monthly by the  Bureau of Labor Statistics as the "headline" inflation number. The "core"   inflation number excludes food and energy price movements, which are viewed   as more volatile than other prices.     
The Fed may be worried that energy-related price increases at the  producer level will soon emerge in the headline CPI. "This stage has not   been reached yet," Mr. Basile said, "but it may not be far off."
